Less than a year ago we purchased a home and adopted the new chicks that lived there. We have 2 Roosters and 3 Hens. They are about 9 months old now. Everything was good and the 3 Hens were laying eggs. Then the top Rooster started pulling the feathers out of 2 of the Hens. Their backs were almost bare. In the last two weeks those two hens will not leave their roosts. I haven't even seen them eat or drink. If we pick them up and move them from the roost, they will just hop right back up into the roost. They look terrible with the loss of the feathers (which don't seem to be growing back) and how small they seem to be. We've checked for eggs and they are not laying. Any ideas?
