I'm planning on getting my first group of chicks in a week or two, and the idea was that I'd keep the brooder in the garage with the heat lamp. I've read up a ton about how to set up the brooder and the chicks needs, including that they should be protected from drafts and fumes. My garage is a tight two car garage, and both my husband and I park our cars in there. The brooder box is solid to encourage protection from drafts, and we always open our garage door before starting our cars. My question is, in these cold winter months, is the garage door opening and closing too much of a draft or stress on the chicks? Thanks for your help!
