My vet was just here and she bought it was too early for a guess. Anyone here willing to venture, I'd appreciate it. This bird is substantially bigger than my Barred Rock, born the same day, but equal size to my NH Red. Almost positive those two are pullets.
This chick was born 4-17, so still pretty young. It's the only Wyandotte I have. But, all the other chicks (Barred Rock and NH Red) have cute little upright, short tail feathers. This one has a much bigger plume which points down.
