Or vice versa? I have a bunch of regular-sized EEs, none of which appear to be roosters (although I'm pulling for one, who seems to want to be). Through a chain of events, I hatched out a single chick from a dozen bantam Ameraucana eggs (the real deal). If that chick turns out to be a rooster, can I put it in with the full-sized EEs (introducing it properly, of course) and get fertile eggs? If it's a pullet and the other EE turns out to be a rooster, would it be safe to let him breed her? I do plan to get more bantam Ameraucana eggs next month, but if I can't I'd like to try to improve my EE egg color when the time comes.
