I took in 7 Cornish crosses who were the unwilling participants in a kindergarten hatching project. I have forever homes lined up for them, but only if they are hens, not roosters. At 7 weeks old they have all their feathers and are the size of my Longhorn cross. Two of the pullets have tiny combs and no waddles, four have medium combs and waddles, and one has a large comb and waddle. Please, please, please tell me that the medium combers are probably still hens I can post a picture later today/tomorrow, but I have someone coming this morning for two hens. Help!
