I ordered chicks from McMurray, they arrived yesterday, cute little boogers. Anyway, the hatchery tossed in some extra chicks for warmth in the box, but I have no idea what they are. Not knowing is making me crazy! All the extras are yellow, and I think most are white leghorns, but two are different from the others. They have marks on their backs. Plain yellow/orange legs, no leg feathers. Any idea what they might be? Are they also leghorns or maybe Americaunas? Something else? Thanks!
