I have two hens, sisters, who raised five chicks for me, kind of like a pair. The chicks are about three and a half months old now and while they still all travel as a group, they are pretty self sufficient now. The two hens still fuss over them like they are little babies and it is quite cute to watch them, actually. But I wonder, when will the adult hens start laying again? They are my only chickens which lay white eggs, so it is obvious they have not been laying any. They did not lay for about two months during the broody stage (took awhile for me to give in and give them eggs) and now it has been a long time since they had any eggs. They are eating layer pellets and getting oyster shell as well as free ranging within my yard. Is this normal? If it matters, the hens are Russian orloffs. Any advice about this is appreciated!
