All of the 4 week olds were hatched by me, the last 2 were hatched at the local high school as part of a Vet Science project. We are not sure on breeds, but I think it's pretty obvious that the white one is a pullet and the barred is a cockerel. 4 week old Cuckoo Marans - Cockerel 4 week old Cuckoo Marans - Cockerel on left, Pullet in the middle 4 week old Black Orp - Pullet? - very small comb, no red or pink at all 4 week old Black Orp - another Pullet? 4 week old Cuckoo Marans - Pullets 7 week old. Possibly Leghorn? Pullet? 7 week old. Possibly Barred Rock. Cockerel!! Anyone have any other ideas?
