Our rooster, Foghorn, has been losing feathers. He has an almost bare spot on his chest and another in the center of his tail feathers. I saw Annie (one of our two hens) reach in twice and pull out what appeared to be the stump of two tail feathers from his "booty." She sneaked up behind him, grabbed the stump and yanked it out. Do roosters molt? Could this be the problem or something else? I see feathers of his all over the run and coop.
