My daughter got 2 chicks from her Agriculture class in school. They are now 5 months old and was suppose to be both hens. Needless to say, one is a rooster and Im trying to give him away so I need to know what breed he is. She also got 4 more chicks that are 2 and a half months old and we believe that 3 are roosters, none are crowing yet but how do I know for sure that they are roosters. We think the lightest color one is the hen. Sorry its a bad pic.
