Yes, 'red light' is better than 'white light'. Red light calms them down makes them less likely to peck at other birds.I currently have my baby quail in the basement and I’ve found it’s a lot easier to feed and water them if I only keep the heat lamps on and no other lights. If I turn on the lights in the basement they flip their lids when I reach my hand down in the brooder. Is it ok to just have the light from the heat lamp? It’s the red light.
The only birds I know of that do better in 'white light' are partridges. For some reason 'red light' makes them 'bunch up'. Partridges tend to bunch up in darken corners, white light prevents that from occurring. Another way to prevent 'bunching' is to have a circular brooder.
