I just happened to stumble upon this and wanted to share. I had changed my red bulb to a black reptile bulb for helping w/ night time sleep. My chicks were about 2 1/2 weeks old and started getting aggressive w/ each other even w/ the red bulb. The black bulb helped them stop being aggressive at night time. When I put the red bulb back in during the daytime they immediately went back to being aggressive. I put the black bulb back in and they stopped and have been friends ever since!
