Many of you are likely to use fluorescent tube lights in your aviary….

Following the European ban of certain types of incandescent light bulbs, fluorescent tube lights have now come under the microscope. Standard T8 Halophosphor fluorescent tubes are being phased out, with production being halted and the importation of them being banned.

With these fluorescent lights being phased out, many people who use them are either unaware of the legislation or unaware of the best and most cost effective method of replacing them.

Below are some FAQ’s with answers to help T8 users avoid confusion and unnecessary expense.

• Why are these fluorescents bulbs being “phased out”?

  In the effort to reduce energy consumption, carbon emissions and to improve the performance and the efficiency of lighting, the European Union have agreed with European lighting manufacturers to cease the production and importation of standard Halophosphor T8 tubes (normal day to day fluorescent tubes).

• How does this affect you?

  As the European stock of these standard type fluorescent bulbs is exhausted, users of T8’s will be required to make a simple change to Triphosphor fluorescent tubes. Triphosphor tubes are a direct replacement for Halophosphor and negate the need to rewire, replace or in any way make modifications to your current light fitting.

• What’s the difference?

  Triphosphor T8 fluorescent is a direct replacement for Halophosphor T8 with no need to adaptor any part of your fitting. Triphosphor tubes are an upgraded version of Halophosphor tubes with longer life and better quality of light, using less energy and reducing carbon emissions.

• Why do they cost more?

  At first glance Halophosphor tubes look far cheaper than Triphosphor tubes, due to their relatively low purchase price. However, the Triphosphor tubes are much longer lasting than standard Halophosphor fluorescents and therefore they can end up costing as little as or even less than the bulbs they are replacing.

• Is there a difference in the quality of light?

  Colour rendering index (CRI) is the percentage of colour that would reflect from the light source to a object then to your eye. Standard Halophosphor tubes are around 50%, Triphosphor tubes are rated around 80% giving you much greater wealth of colour.

When I wrote “The Challenge”, I omitted a guide that first appeared in my first book – “Best In Show”, published in 1974.

So, I am now pleased to correct the situation with this handy reference guide for breeders, enabling them to know exactly when to assist the struggling chick and particularly when not to intervene!

As we know, opening too early can reveal the chick which still has not absorbed the yolk into its body and it is pale and weak. The outcome is death! Opening too late and the chick for various reasons also dies, unless helped a fraction earlier. Close observation and timing are therefore vital assets to your husbandry.

Remember, if it is the first chick to hatch, leave the empty shell in situ and move the tiny chick to a pair you know feeds small hatchlings really well to increase its chances of survival. Also bear in mind that a pale chick may not make much squeaking noise.

It is the bright red chicks you want. A red chick will be fed as the hen will feed it easily, but if the chick does not call because it is exhausted and weak it may not be fed and will die.

Fanciers frequently blame a hen for “crushing” tiny chicks. Occasionally this is true especially when young hens are in use and have no idea what to do when a chick hatches. However, the most common reason is that non red chicks have not demanded to be fed and consequently look “flattened”.

At my stud at “Tanglewood”, I managed to lay my hands on an incubator. This is used entirely for two purposes, but strangely not for hatching eggs!

It contains large plastic eggs, from Germany in my case, plus a surgical mask that is there to warm up “cold” eggs that a hen has deserted, or, kicked to one side in the nest and also for chicks that have similarly been left to go cold.

Deserted chicks may often look dead and white, but it is surprising after a few hours how some can recover using an incubator. Remember it is vital to attempt to save every chick for your end of year tally and some of those could be Best In Show possible contenders.

So, where your personal budgerigar stud is concerned, ask yourself, when your birds are getting to look really ready to start breeding, is the Ring Issue date more important than grabbing that moment to begin your personal season? Personally, I grab the moment these days and “get a round in” from perhaps a third of the stud and get results on the perch early with whatever rings I have to hand. I then have a cushion under me if the birds paired later, to meet the following years’ ring issue date, fail in breeding condition to meet such a specific date. Many breeders work to whatever the established issue date happens to be – often with poor results or worse. Breeding fitness first is vital!

As experienced breeders will know, our birds need first class daily attention and a feeding technique that supports high fertility and hatchability. However, a few added words of advice. Many breeders have large outside flights but small inside flights for roosting and feeding. Sometimes these inner flights are too small and the birds are cramped. As a result they become stressed, but we do not realise it. Birds need roosting space for each individual because otherwise the more robust birds pressurise those who are less aggressive and shy. Overnight can be especially stressful and dead birds can be found the following morning for no apparent reason.

In flights and stock cages, budgerigars need to chew. Fruit tree and Silver Birch branches are ideal and I know Eucalyptus branches are popular in warmer countries. Seeding grasses can be selected as well, but be careful that your local farmer has not sprayed his crops if you are choosing grasses close by. I have also found that if you visit an aquarium shop, you will find mis-shapen pieces of wood which have holes everywhere (for fish tanks) which last forever. A number of these piled high give added interest and if you scatter softfood throughout, as I do, they provide endless active searching through nooks and crannies. These all keep the stock very active and this is so important when we try to breed with these large heavily built hens that are so common these days, who otherwise just sit there all day.

To summarise. Keep your birds active. You are the provider and it is your job to see to it as part of your avian husbandry. The results may then pay off so that you can pair your birds at anytime of your choosing with finer results all round.

Second Birdroom Fails To Perform

The story was highly significant as the reader will quickly understand. It concerned a completely baffled fancier who had built a second birdroom alongside his highly successful existing structure.

The earlier birdroom had 16 cages and was breeding winners which were in high demand – hence the need to expand. The breeder decided to duplicate matters. The new structure also faced in the same direction. Some birds, upon completion of aviary number two, were transferred to the new room with a great deal of optimism.

After a few weeks it became obvious that breeding was poor and the question was “Why?”. The old birdroom was breeding at the same time and producing good numbers of chicks as usual. In the new room, infertility abounded and what chicks there were, were not being fed properly. Dead tiny chicks appeared regularly.

Possible Solutions

The situation was baffling. Heaps of thought went into determining the cause of the problem. Feeding was identical as were the night lights, heating and so on. There was also plenty of budgerigar noise so attention turned to the fitness of the stock in both birdrooms, but could a virus be affecting matters? Thoughts turned to a discussion with an Avian Veterinary Surgeon.

The vet pointed out that a new room would possess a colony of bacteria and viruses that would build up naturally after the “new” stock was transferred. However, it was feasible that a group of “bugs” had intervened and it was this factor that was the underlying cause of infertility and hatchability.

“Perhaps the aviary needs fumigating?”, was his suggestion.

It was at this point that I was approached. Our intrepid fancier called me. He went through the whole matter in great depth, with me, as I always do, making notes throughout.

He was thinking in terms of using a sulphur fumigation process, but I know this turns everything in sight a dirty yellow, as well as killing off most bacteria and fungi. (You cannot kill a virus!!)

I knew also, from experience, that because you are so committed to your problem, there will be blind spots that you miss, so you need to come at the problem from a different angle.

I rang down and thought about it for a few days. Everything was duplicated and I could not work it out which annoyed me.

We Saw The Light!

I rang him back.

We went through it all again, with me looking for a new clue in his chat with me. I then asked about his night lighting. His answer was fine – it wasn’t the night lighting.

Then he said, “the new birdroom main lights are on from 07.45 hours until 22.00 hours, non stop”. Suddenly I saw it. “Why are they on so long?” I asked. “Oh, it’s because the new room is in a darker area under some trees” was the reply. “And the old aviary lighting hours, what are they?”, I asked. “They are different because that aviary is unaffected by trees, so the lights come on at at 07.45 hours, off again at 10.30 hours until 16.00 hours, when they come on again until 22.00 hours and off for the night.”

There was his problem. His birds in the new birdroom were not getting any rest at all in daylight hours. They were hyperactive, but this did not mean that they were sufficiently rested to effect good breeding results.

All breeders of experience know that approaching midday, any aviary in standard timed lighting conditions as this breeder’s old aviary was timed, have a good two to four hours rest.

The aviary goes quiet for this period. Then once rested and the 16.00 hours lighting returns, the birds are active again. The hens come out of the boxes and excrete and are mated immediately.

Lessons Learned

There was the problem and in about 8 weeks both aviaries were churning out chicks as a result of this fancier’s good husbandry which was only spoilt by a small error.

Both of us had learned something in the process. It just illustrates how something small and innocent affects good breeding results.

Obviously I cannot guarantee this applies to sunnier climates – compared to those that we have in the UK, but the fact that birds have a requirement for rest periods should not be lost.

Aviary Maintenance – External

Let me take this year as an example. It is November. In the last 6 weeks I have been working to get the aviary “winterised”. A very cold one by UK standards is forecast. So, having a cedarwood exterior, it needs treating every three years without fail. That has resulted in it still being as good today as it was when I purchased it in 1971. It would be massively expensive to replace as it covers 1200 square feet (110 sq metres).

The window frames need constant attention (I hate painting!) and the roof needs to be checked for leaks. Virginia Water is heavily wooded so leaves are a constant problem, hence the gutters must be checked too. Elbow grease is essential. What all this is about is not having to attend to problems that could arise in very bad weather. Dealing with a leaky roof in wet conditions is not funny and the disturbance to the breeding pairs also has to be anticipated.

Aviary Maintenance – Internal

Moving inside, I am fortunate to have bought my cage units from Reinhard Molkentin back in 1988. They are made of a composition of a plastic nature (very heavy) with a aluminium framework. They never need painting (I like that) and just need washing to bring them back to new. They are in many aviaries in Germany, Jo Mannes’s aviary being but one example. Expensive, but in long term well worth it.

All electrics are checked, especially the heating systems and thermostats. I used to have tubular heating but this was far too expensive to run and inefficient as the air was not circulated well. These days I use (Dimplex) fan heaters which work very well provided you are attentive to de-dusting them out regularly.

Nest Boxes

Coming to nest boxes, of which there are currently 56 in use (and being double boxes with one inside the other it means 112 really have to be cleaned), I use “VIRKON® S” a great deal. All are finally dipped into this solution and allowed to dry off. This appears to contribute to a maximum of 5 or 6 minor French Moult birds only, from approximately 300 bred per annum. They are affected very little and if stripped from flights and tails at 4 weeks, then recover fully.

Incubator

Some time ago, I bought an incubator. I use it to keep oversize plastic eggs warm at the same temperature as real eggs. When the first egg is laid, in goes a plastic one. Use of false eggs has the following advantages:

• They prevent those strong day old chicks being crushed before you can get to them if they have not been fed. Note: Weak chicks because of poor management techniques will not survive anyway.
• They can stop a pair smashing their own eggs – they get fed up trying to break a plastic egg.
• They retain heat while in contact with eggs that have been left for too long thus saving the developing embryos.

Increasing Fertility

I am often asked what I do to prepare for increasing the fertility in my stud. Here are several thoughts for you.

• Make sure you have a round-the-year source of vitamins A & D – in moderation. Overdo it and you will be in trouble, as both are stored in the liver and not excreted.
• I use a powder product called Hormova. It again is present in the flights and cages all the time.
• A certain “X” factor which you can buy in specialist horse tack and feeding shops – but that is up to you to think out and track down. Sorry, but we all have our little secrets!
• Never give massive doses of antibiotics across the board with the exception of treating accurately against “yellow belly” in tiny chicks before breeding and the same again when breeding stops. This practice also improves fertility in my experience. I only treat a health condition which is preventative. If you start playing around with growth promotion then you risk ruining the whole stud – and it is banned anyway and rightly so.

Seed Mixtures

I now turn to the seed mixtures which we all use. I am after every chick I can get by every means possible. Seed that may have been harvested too early (and that applies to millets sometimes), is at risk of having micro fungi attached because of the dampness. Note: You can always test a bag of seed for ripeness by making a fist and plunging it down into the bag. If you meet resistance you know it is not fully ripened. Add any mites to the fungi, especially in millet sprays, and you have a recipe for loss of chicks. To kill off everything mentioned, use a super product from VETREPHARM (in Hampshire). This is put in the bottom of each bin before loading and fumes over 48 hours. The seed is unaffected and 100% safe to use.

Avian Flu

To conclude, a word about Avian Flu H5N1. Either keep the stock under cover or make certain that any indigenous wild visitors cannot excrete into the outside flights. As of November 2009, DEFRA has designated that the UK is free from any reports of Avian Flu. However fanciers should check the DEFRA website for any changes.
