The pink, (not yellow) on the bottom of feet and leg are correct for a BA when young. The beak may be all black preferred or black and horn color, but not yellow. I hope that clears that up. Yes the nubs in the last pics may be spurs, but I also had a hen with spurs years ago.

That is the color - horn! I think the beak is getting more black every day. Yes, that was very helpful. And I won't worry too much about the spur nubs for now. Thanks!
