The daddy, we think is a white easter egger who had rust on the wings. The mama is a mystery. Came from a brown egg. I have a splash orpington, barred rocks, black cochins, buff orpington, a delaware barred rock cross and a amer. barred rock cross. The chick has very thick "fur" and it feels different from other chicks down. Who do you think might be the mama of this chick?
