I ordered 25 chicks from a hatchery earlier this year and they were delivered the first week of April. They were from an "Ornamental Layer Collection all supposed to be pullets. Yesterday one crowed! It's the white one with the black head. Since the I've been really watching them, and am afraid that there are at least 4-5 other roos! Can anyone tell if any of these are roosters? Or if you know what breed any are, that would be helpful. Thanks!
