They are 8 weeks old, breeder says they are pure bantam Cochin, but I suspected at first that they were crossed with Polish. Went to her house, and saw some Silkies. Cochins don't have crests, so then I assumed they were crossed with Silkies. Well guess what? One has five toes on one foot. Both have yellow legs and no black skin. I'm hoping they're both pullets, but I'm scared of the comb development on the one. What do you think? Could the first one be a roo? Above is the second one, and comb is much paler and smaller. Bottom two pics are of each individual, the last one being the reddish one that I fear is a roo.
