So cute and pretty! Love the color! I agree that it is too early too tell. Maybe post again when they are older, maybe at least 2-3 months old and we should have better guesses. The one in the middle looks like its face is getting a little red and saddle feathers look suspicious, maybe a cockerel too? The one in a back is a pullet for sure though. Do you know what type of combs that they have? I can't really tell. If they don't have single combs they can't be Orpingtons.
