I set 25 copper maran eggs On day 18 I candled and removed 1 unfertilized egg. Since I have been having problems with the temperature, I covered the incubator with a heavy yard rug to hold the temp close to 100. It usually read 99 although the last couple of days it did drop to 97.5 I removed 8 chicks on the 22 day I removed 8 chicks on the 23rd day 23rd day I checked the remaining 6 eggs set each egg in a bowl of warm water. 1 of the 6 sunk. It had a chick in it that lived until the last day or two 5 eggs floated but no movement. I opened the end of each egg and found one chick that had pipped through the membrance but not the shell. The other 5 chicks had obviously died the last day or two. One membrane was white, A couple were turning white. This was one of my best hatches. I have been having problems with temperatures. So far have replaced the thermostats in 2 of my 4 Genesis 1588 and have another one to replace. Might have to order the 4th one. Would you be happy with 16 out of 24? To me that is not very good. Am I too hard on myself?
