We have chickens that are about 10 weeks old. We got them altogether, 3 Ameracaunas, 3 Buff Orphingtons, 2 Barred Rocks and a Rhode Island Red. They all were getting along fine until today when I watched the 3 Ameracaunas attacking each other like Roosters, in their run. I hope I don't have 3 roosters! Is there any way to sex them or identify if they are roosters at this age? We have the same mix of chickens years ago and never had this issue.
