We have two RIR chicks that came from the same hatchery batch on 4/4. Though they are almost the same size, one has more distinct markings is far advance of the other in featheringthat the other (and all the rest of our chicks too). She even has a few tail feathers. No comb yet but I am suspecting the more feathered hen is NOT a hen at all... Any thoughts? ....My husband is thinking BBQ...
