I was showing my rooster at a fair yesterday, and a small boy asked if I wanted to buy one of his silkies. My flock had been reduced to five, thanks to a dog, so I said yes. I bought a six month old silkie rooster, and discovered that his "flight feathers" (Yes, I know chickens really can't fly) were dry, brittle, and all twisted and broken. It looks kind of like split ends in hair. Is there anything wrong with him? Or rather, any way to fix it?
