My Flock is made up of all Rhode Island Reds(1 Rooster 35 Hens). The problem the Roo is alot bigger than the hens (all same age) and in the mating process some of the girls lost some to alot of feathers. I have removed him(to his private pen,which I don't like and sure he doesn't) but haven't noticed any new feather growth.Do they have to go thru molt or should I do something?????
