People might not agree with me, but my chicks are in the garage right now. It's not heated, but is insulated, and if I need to open the garage door, I have something I cover the top opening of the brooder with partially to keep drafts out. The chicks never huddle under the lamp, and the temp has stayed consistant so far. I am using one 250 watt bulb. If I am unable to maintain the 95 degree temp, I'll bring them in the house, but it has not been a problem. I have allergies, and wanted to try to keep them in the garage if possible, because of the dust. We raised chicks in our garage last year, but we got them 5-6 weeks later last year.
I did lose one chick yesterday, but that one was smaller than the rest, and weak. I do not believe it had anything to do with where my brooder is. The rest are active and well.
