My house has been taken over by chickens. I have FOUR different brooders because as they get bigger they need more space so I keep dividing them up. I don't have a light on the older ones anymore (hatched on 1/7) If I put two 100 watt bulbs (one for back up incase God-forbid one were to go out during the night (because you never know) do yall think they would be ok?? I have a great place to keep them (completely draft free and preditor safe). It is 60 out there right now and usually is in the 30s at night.
