I have a red light in the coop (25 watt) for heat. Is it ok to leave it on all night. It is a mounted fixture so no fire will start. Just wondering if it is too much light for the girls. The 8 RIR's are giving me 7 or 8 eggs per day. I don't want to over work them!
So you will need to modify that with the changing hours in the day. Are your RIR's fully grown and feathered and large fowl? It is up to you of course on how much heat you want to offer adult hens, but with our Large Fowl birds, we don't heat their roosts, but if yours are used to having heat at night or might be in a situation where you see that they need heat by all means offer it
