Going to be winterizing my coop tomorrow so its much warmer for winter. My husband asked about putting a light bulb in for warmth that would hang just about a foot over where they roost. I told him a white light would not work because they would bother each other all night. They can see the light from our back porch flood lights all night and I often find them curled up sleeping not paying any attention. Could I put a 250W red light bulb in their old brooder light and hang it in there for warmth? Any other ideas for heat source other than a heater?
