Hello, hopefully the pictures I put on loaded okay. We have six nine or ten week old chicks that were sold to us as three Barred Rock pullets and three Buff Orpington pullets. One of the BOs is different from the rest. Very dark red/gold color with some black tail feathers coming out. I was wondering if this is a Rooster? Hen? Or even a Buff Orpington at all? Could he/she be a mixed breed? It is also smaller then most of the other chicks and seems to be at the bottom of the pecking order. If it were male I would think it would be closer to the top of the pecking order. Thanks for any input.
