Well, just an update. I took the little he/she back over to the guy I got it from to help me sex it. At least he said he couldn't blame me for the confusion. He says it is either a cockerel with really late spur growth and really round saddle feathers or an extremely dominant pullet. At least his boy really wanted it because of it's fun colors, so it will have a happy life one way or the other. He is 80% sure it is a cockerel, but says it is pretty bizarre that it has characteristics of both sexes. So thanks to everyone for helping me out and we will see (at his place) what it finally turns out to be without my girls having to deal with it being such a tyrant in the coop! Thanks again!
