I have a rooster that was "plucked" by another rooster before I got him. I have had him for 3 months now and there has been no new feathers. Someone told me that I need to pull out the broken feathers because the whole feather needs to be removed for new ones to grow. Is this true? That seems painfull. He looks pretty beat up though, no big tail feathers and only "stubble" so to speak around his neck. Any help?
