My son is a true chicken lover!!!! We bought him 2 last spring that turned out to be roosters. We now have 6 more chicks purchased from My Pet Chicken that are 6 weeks old. He's concerned one of them is a rooster, which we can't have because we are in the city limits. Please look at the picture and let us know what you think. The comb is barely existent but what's there is much more red than the other chicks' comb (although they are not the same breeds). Also the waddles are turning more red and look larger than the others' on different breeds. The chick is supposed to have been a Black Minorca, but he's beginning to think it's a barred rock because of the markings. Thanks!!
