I am no expert but, just finished raising 20+ Shamo chicks and now have another 22 shamos, asils, Malays and Sumatra in the same XL dog kennel that is my brooder. I always use red light and have only had trouble once. When they where about 5-6 weeks and had been moved outside to a larger run but weather went cold for South Florida and I brought them in but in three separate groups. Two days later back to the run and a battle royal erupted, lots of Peking and striking. I stepped in and let their blood cool a bit and slowly reintroduced and all is well now (knock on wood). I am currently building a lg grow out pen to keep roosters and younger games.
