We got our flock last month. We are first time owners, and loving it. When we got the 8 hens the Barred Rock was in perfect condition and the oldest. Next was the two hamburgs again with just some peck marks on the head. Then came the Easter Eggers they were all missing feathers on their back in various degrees. The EE roo that came with them was raised with the girls and he 'loved' them a lot. We thought he was too rough, as we caught him holding the hens down and stealing food from their mouths at treat time. So the previous owners took back the roo...and had a nice dinner. So roo gone, new banty roo in. The feathers are not coming back, it seem like once we get some growth the new growth disappears. Is this from pecking? I have included pics. What does this mean for my 13 baby chicks?
