what breed are they because my chicks looked just like that and they are IDENTICAL to the latest picture x x
My birds are Langshans. They should have more leg feathering on their legs, but lucky me just found out they've been pecking their own leg feathers. A quick spritz of spray and they've stopped that. Hopefully it was from boredom.
If yours don't have leg feathers, they could be:
Jersey Giants (the underside of the foot should be yellow)
Black Plymouth Rocks
Black Minorcas (will have white earlobes)
If yours do have feathers on their legs:
Black Brahma (will have pea comb)
