Thank you so much for your answer. I thought he might be a Welsummer, but the comb wasn't right.
Don't know where he came from. My other chickens (including two roosters) don't seem to bother him. He didn't sleep in the run last night and I didn't expect him to. My chickens run free range...
I have a small flock of chickens. Yesterday when I got home from work this rooster was in the driveway. Not one of mine. No one around us has chickens to my knowledge.
