These are three week old chicks.... I think three of them are RIR and the yellowish one is a Buff Orpington. Please clue me into what GENDER you think they are! RIR? Baby 1 or 2, they both look alike! Baby 1 or 2 also, different view. Baby 1 or 2 also... RIR?? Baby #3 has much less feathering and almost no "butt" feather. The backs of Baby #3 and Baby #4 Buff Orpington? Less feathers that Baby #1 and #2 THANKS!!
