incubation temperature

Post by leytonryan on Fri May 09, 2008 5:19 pm

I know i am probably the most annoying person here but, i am new at this and need help. I have a home made incubator and have managed to hatch some chicks. The thermostat turns the light off at 38 degrees and goes on at approx 34. Anyone no if a know a better thermostat, is the range between temp very big.

Hi Leyton

I know nothing about home made incubators, but if you PM Horsley-Anarak or Andoy they might be able to help, both have built really sucsessful incubators.

Heres a couple of links to H-A's incubators -

Hope this helps until someone with experience comes along

hi Leytonryan,

the main obstacle with making a home made incubator is finding a thermostat that keeps a temperature tight enough to the ideal of 37.5C If the temperature swings between 34 and 38 you're going to get a very poor hatch. Many will not develop, partially develop or fully develop and just not hatch. I've managed to find a great thermostat, but can't get it to work so I'm sending it back to the manufacturer. I now use my home made incubator a hatch box (to keep my incubator clean) or a temporary brooder.

I think that the sensitivity of the thermostat is very important.

From my experience you want the heat source to cut in and out over a very tight temperature range.

The best I have found is a Velleman kit K2649. ( this is the one andoy cant get to work)
If you Google this you will find where you can get one, It is a bit tricky to make but not too bad.

This will cut in and out within about 0.3 degrees C, which I think is good enough.

There is also another Velleman thermostat available on Ebay, and this is already made.

It is not as good as the K2649, but should be OK.

I used a light bulb in my first Incubator, but at the back of my mind there was always what if the bulb blows?

Resistance wire is far more long lasting, I use under tile heating wire. I find that 2m with a 12v supply gives good heat.

If you want some PM me and I will send you some (you can pay the postage).

Happy building

Thanks for your generosity, will try this time again to see what the hatch is this time. But now that you've told me that my poor hatch is porbably affected due to the temperature flactuating 4 or 5 degrees. i am going to wait untill the end of the month when this hatch should have finished as i do not want to alterate the temp more than it is.After this i am going to buy a new termostat, and throw out the one i have. Anyone know of a mechanism i can use to turn the eggs automatically? preferable some pics or something.

Thanks
