I have never had an Ameracuana or EE with yellow legs. I was thrown way off when I got my chicks last month because she has yellow legs and face tufts. I know that can happen but I have never had one.
That one has a girly shaped comb, but the legs seem a tad thick. I just had the experience of an Ameraucana cockerel with a girly shaped comb. Fooled several of us, then it got red way too soon for a pullet. That's when I noticed the legs were very thick and it was actually larger overall than the other known cockerel. Its about 11 weeks old now, but the comb was very pinkish two weeks ago.
