Then it's safe to say that the ones with pink combs are male. The Dominique may have the darker barring of a pullet, but that comb is way too developed and pink, indicating that it is a mixed breed cockerel.
Need help with breed and sexing of my chickens - Page 3
The only cockerel I see, is one of the white ones, with a larger, more prominent white comb. The rest seem to look like pullets. The white chickens could really be anything, my guess is a hybrid of some sort. The speckldey one, similar to a Maran is a Dominique pullet. The two pullets with gold leakage seem to resemble gold laced Wyandottes.
