I have a flock of 10 hens and one rooster. 8 of my hens are bare backed and half of them have lost feathers on their heads . My question is, is my rooster doing this to my girls or are they molting??? I have watched the roosters behavior with them and he don't seem no rougher than a usual roo would be. If they are molting, isnt this the wrong time for that? They will be a year old the end of April. Any help will be appreciated.
