We brought home two Ameraucana chicks and one Welsummer, and lost one the first few days. Our local farm gave us a replacement, but we have no idea which breed we lost or which breed we brought home to replace our lost chick. We have at least one Ameraucana, or maybe two or maybe three. We're just beginning our chicken adventure and I can't tell the difference. Any insight from this pic? They're 4.5 months old. Thank you!
