#1 has a single comb.
I think she's a RIR, I looked at the buckeye specs and there is no charcoal line down her back. She has bright yellow legs.
Well, no decisions to be made until we're 100% sure she's a he. I'm getting to know our brown leghorn more each day and what a sweetheart she is! I'm going to have to hang with her a lot more so she's better peep socialized before I place her with the flock.
