I have twelve 4 week old chicks that are supposed to be all female. I got 2 of 6 different breeds. I was supposed to get 2 Barred Rocks and 2 Cuckoo Marans. Not sure that it really happened that way. At first, it seemed easy to pick out the Cuckoo Marans and the Barred Rocks. Now, one of those 4 looks different and the other 3 look very similar. One developed a comb before the others and her feather pattern is different and she is slower to get her feathers, she's Sea Salt. In the second photo, is one of them a Maran? They are Ella and Sugar with the little Wyandottes (Mara and Goldy) in the front. The 3rd photo should be a Barred Rock, she's Bella. Thanks for any help.
