Does a red light cause aggression?

I think it was the scratch and new strip curtain. Now I’m feeding scratch only in the morning, and one strip of the new curtain is tucked up so the chickens can see thru to the run. Peace has been restored. The heat lamp was on for two nights when it was below zero. No fire, no frostbite.

Awesome, yeah I somehow got ahold of 6 pieces of french toast before bed the other night. It didn't translate to a restful sleep either.
