This is my first batch of this breed and I hatched 8 chicks. Two look totally different from the rest and are pullets for certain.

Still....one in particular has an almost whitish-pink comb, not the Pepto-Bismol pink of the others, and another one seems not very masculine. The first two pics are of the same bird and the last pic is another one:
