My baby chicks are hatching but so far I have lost 2 and a third isn't looking so good. For some reason they are flipping on their backs about 12 hours after hatching and they I find them dead. I don't understand. They look great up until then but once they start flipping on their backs they do it over and over and over again. The ones I have found doing it I will find on their backs dead within the first 24 hours. What is going on. Can anyone help me?? I can't watch them 24/7. I check them often but I don't know what to do.
