I have 5, 6 week old buff orpingtons. They are from pure bred parents, and the parents have white/pink legs. One of these youngsters has the right colored legs, but the others have light yellow legs. Do the legs sometimes lighten as they get older? Or do I have cross breed Orpingtons on my hands? They are all from the same batch, although the one with the white legs is a little smaller.
Any answers will be appreciated!
