A quick question about heat lamps. We have some fancy breeds that are not cold tolerant, and when it gets below zero degrees outside they do better when they have a little heat. We also supplement them with a few extra hours of light (a 40 watt bulb) in the winter to keep up egg production. I've read that chickens need at least 8 hours of dark and rest at night to stay healthy. Our mini heater from last year kept getting full of dust, so we'd like to move to 2 secure, stable heat lamps. Will the red light from the heat lamps disturb their nightly sleep or mess with their daily biology? I know that the white light helps them lay more eggs, but what effect does red light have?
