Recently got 20 chicks. 2 light brahma's have turned out to be roosters. They are now 14 weeks old. They get along fine. Can I keep them together? They are in an enclosed coop/run due to predators with the 18 girls....10 x 20 ft. coop with a 12 x 36 run. They are gentle and will sit on my lap. I would like to keep them together. I could move one over to another coop where I currently have 4 buff orps and 2 EE's. Would that cause a problem in that coop? thanks!!
