Several months ago my husband was working in the yard when he called out to me about one of the chickens being over in the side yard all alone. I asked which one? He replied the red with white tail. Not recognizing that description for any of our girls, I went to see. Apparently someone dumped this bird off here because it wasn’t one of ours. So it has been here since but has us confused as to what it is. I think rooster, hubby says hen. It has never crowed or laid an egg. And still does not mingle with the flocks buts stays in coop all the time alone. Seems healthy, eats well, poops ok, active. I have never seen any of ours bully it. I named it Gypsy. So, what gender/breed?
