I think the ones with the bigger, pink combs are also bigger birds, they have more white in the barred cuckoo birds, so yay! My freezer will be happy and I'll hopefully still have several girls. I think I have a cuckoo and a barred pullet, they both have very small orange combs and are smaller. I think one is by herself on a concrete block, don't think I included that picture. And still hoping the black one with the small comb and ear muffs is a girl.That brown one in the first picture also a girl. Those one's that have the larger darker pink comb's could be boy's.
