Peter&Sam :
Hi Sam and I are completely new to owning chicks. (Sam is my grandson) We have tried three times with our incubator with no success.
The chicks Have died in the shell. Our own chicks eggs. Not many were fertile.
Kept the temp at 37.5 and humidity at between 30 and 40. turned up the humidity to 50 at day 16.
on day 18 tomorrow.
Maybe we are all wrong? Tips welcome. Hope we have some success this time!
Sam and I are from Yorkshire England. We found this very interesting and informative site and have been following the comments on various subjects.
We are really getting into this chick keeping.
My husband and I visited England in 2002. It was wonderful. Everyone was so friendly. We went to the Windsor Dog show, great! I was able to talk about my Italian Greyhounds with many knowledgeable people.
It sounds to me as if your humidity is too low.
I keep my humidity at 55 and turn up to 65 for hatching. Now, that said, you will get many opinions about humidity, and it partly depends on the humidity where you are. I am think that Yorkshire is probably lower in humidity than where I am, which is West Virginia, which could make a difference.
Still, I would bet that you need to turn up the humidity.
I am embarrassed to say that I don't understand the temp--although I am a nurse, I am retired, and I am so used to thinking in Farenheight that I no longer can think in Celsius. I keep my 'bator at approx. 99-100 degrees F.
Good luck with your eggs!
