I have four white leghorns, all sexed as female by MPC. These four are IDENTICAL in feathering, size, and comb size - so so far I think I have four of a kind, whatever that kind may be. I can't even tell them apart, unlike the RIR. They are four weeks old and have zero pink in the combs (although my picture makes it look otherwise) - all have yellow combs, but I notice the combs are much larger than my RIRs (also sexed as pullet). Do leghorns normally have larger combs as chicks? They have been larger even since babies. My picture is not so hot, as without treats they run to the far end of the brooder like I am an ax murderer. Plus they like that little patch of sun. So.. All boys? All girls? Too soon to tell?
