I bought 6 supposedly 2 yr old hens, they didn't have any feathers when I got them and they still don't, he told me it was from the rooster. The one that was left here hasn't ever gone bald and I don't know her age. My rooster is about 10 or so months old but I don't think he's working, or I haven't caught him working. So why aren't they growing them back?? Is this normal? Egg production has gone down too, I was getting about 6-7 eggs the first month or so, now I'm lucky if I get 4.
