I had a broody hen and wanted mostly Easter Eggers out of the hatch...She had a total of 19 eggs under her...they were all smaller eggs from young hens (born in Feb). All but one of the eight other eggs hatched. I opened up the EE eggs and not one of the had any development in them. I had thought I was just wrong when candling them and that it was just harder to see through them. The eggs came from two EEs both born in Feb also. I had been checking for fertility so, I am sure they were fertile. I would love some input on why they might not have developed. Thanks!!
