With the day and nights getting colder I went to put on my white heat lamp for my chickens to find it wouldn't turn on. I have an open air coop and I think it got ruined in a bad storm we had. I thinking about getting a new red heat lamp because I hear there better for them. With my coop being open aired how long until I will absolutely need a lamp. I can probably get one within the next few days but I'm concenred because it's getting below freezing at night. Please respond ASAP Edit: I went out tonight to check on my broody hen and as i was out there the light went on. I'm still thinking I should get a red bulb though. Does anyone else use a white heat lamp at night? How does it affect your birds? And does the heat lamp need to be over the roost. I put mine over the nest boxes, food, and water. Their roost is on the other side of the coop. I didn't want the water to freeze or the broody hen to get to cold.
