Agreed.A Legbar rooster won't make sex links with anything, and if the hen was a RIR, the egg would have been brown, not blue. If the eggs were a green color, not a good blue, it's likely the breeder hasn't been culling well for breed traits. Autosexing is a trait they still have to cull for, in my understanding. Some birds have muddy traits, and then they're bred and pass that on, and you wind up with birds less and less like a true Legbar. Or, it could just be a mix.
