Those are awesome photos, and beautiful birds, but if it has to be one of them laying (you dont have any other birds?) Then I'm totally stumped. They both look equal in development to me. Easter eggers are essentially a mutt, a blue egg breed (ameraucana or aracauna, I'm not great with spelling) mixed with any brown egg laying breed.. Depending on the brown breed used you can get any variation of feather color, egg color etc. Yours might be mixed with a breed I'm totally unfamiliar with and that could be my problem. If its got to be one of them I'd suggest checking their pelvis width after they roost.. Your only sure way to find out. Sorry I couldn't answer your question, but do reply back once you find out, I'm curious! Best wishes!
