I don't see anything that says buff Orpington.
The white one looks about 5 weeks to me.
The brown one looks like a girl.
I can't see the white one. He must have been shooting around the brooder when you took those photos.

Do you have any recent photos?
I don't think either have any Buff orp in.
I can see how one could be a speckled Sussex cross, but not BO.
