We thought they were moulting and growing new feathers. We have read they do that late fall. But it seems pretty late in the year. Winter is here for sure and they are still dropping some. These are white leghorns a year and a few months old. Most of them look OK but 2 are pretty raggedy. Only 1 or 2 tail feathers, patches of wing feathers gone. So far no one seems to be pecking on them. No raw or bloody sites. Should we do something?
