Blondie does not look right to me.The 3rd possibility; which I find rare. One of our hatchery pure BO is not pure from the hatchery.
I would lean toward this one, Blondie, because she is the blondest of them all.
But idk if BO can be that pale blonde.
Idt it’s SOP.
Buff Orpingtons are not supposed to be that light. Some chicken breeds are known for producing not-right chicks of certain types, but Buff Orpingtons are NOT known for producing birds like that.
So she might not be a pure Buff Orpington. She might be an accidental mix, or she might be a completely different kind of chicken that ended up in the pen by mistake.
It will be interesting to see what color feathers that chick grows. And the feather color may help figure out what is going on here.Get 12 perfect little gold fluff balls; and a blonde with black spots up its back!!!
Take a good look at the comb and the feet of the chick. Buff Orpington chicks should all have single combs, clean feet, and the normal 4 toes (3 pointing forward, 1 back). If the chick has a different comb type, or feathered feet, or extra toes, then you can be certain it is not a pure Orpington. If it does not have any unexpected traits, you will not know for sure either way.1. One of my children accidentally mixed an egg up. Problem with that theory is that the dad would be an Americana & good chance it’d be an Easter egger; could be a few different ones but I do have a lot of “Easter egger” breeds in that pen.
Posting a photo of the head of your "Americana" rooster might help. Depending on his comb type, it might be possible for him to produce single comb chicks, or it might not be. If he cannot produce single comb chicks, then comb type would show for sure which pen the chick must come from (Orpington pen or other pen.)
I would not sell the odd chick as a pure Buff Orpington. It definitely looks wrong, so even if it does happen to be purebred it would count as a cull (which certainly could be sold, but not labeled "Buff Orpington.")My plan was to sell this as pure but idk about that atm.
Given the light-colored hen in your Buff Orpington pen, I would probably not sell any chicks from that pen as pure Buff Orpingtons (because if she is not a pure Buff Orpington, then neither are her chicks, and you probably have no way to be sure which of the chicks are hers.)
