My coop has three hens and one rooster. Three weeks ago my Wynadotte hatched four chicks and so I seperated her and her chicks from the main coop. Now, my rooster is not being aggressive with the remaining two hens, but mounting them so constantly that their back feathers are all gone and one of the hens has taken to hiding in the coop to stay away from him! Is this just because the pecking order has been disrupted or is something else going on? How do I treat the raw backs of my two hens? Any suggestions would really help!
