This is a 7-week-old hatchery cockerel. Is there any way to know at this point if he is a Barred Rock or a Cuckoo Maran? Can anyone tell from these pics? My hatchery says CMs have grey legs and BRs have yellow legs. But I've also read that CMs have pink legs and BRs have yellow. This guy has pinkish with some gray markings. As you can see in the picture with the two barred pulletson either side of him (I'm not sure which they are either) the pullets legs seem yellower and his pinker, but all have grey marks on the legs. Thanks for your input.
