Sorry for another post, but more breed questions! I have three chicks that look alike to me--with the exception that one appears to have a single comb and the other two don't. Does it look like these could be two Dominique and the single comb is a Barred Rock? I ordered two Dominique and two "assorted." The three that look like this are the most friendly of the group. Their feet are lighter/yellow at the bottom with some darker coloring higher in the leg/top of feet. If not Barred Rock, other breed ideas?
