I've been thinking this lavender/self-blue Ameraucana was a pullet for awhile, but now at about 7-8 weeks old, I'm thinking that maybe it's a cockerel. The upper part of the pea comb is more raised now and while not as pink as the one that I'm sure is a roo, it does look like it's getting pinker under the gray coloring. I think I can see the 3 rows of "peas", but I have read that you can sometimes see this also with pullets. In the last photo with the 3 birds (siblings) you can see the bottom bird is clearly a young cockerel, as his comb started to pink up and get raised about 5-6 weeks. The bird in question is in the middle. The black one has a very flat comb and is flesh colored. The bird in question is also challenging the little roo a lot, so wondering if that isn't another sign.
