So my 11 week old chicks have been out in their coop and free-ranging for quite a while. I just have kind of left the heat light up, b/c we used it for heat, and then went on vacation, and are now back. So should I just go cold turkey (ahem, chicken) and just stop turning it on (it was on a timer for night time), or gradually wean them off of it? Any ideas? I didn't want the heat lamp/light to be a permanent fixture, but I also don't want to do something wrong. Thanks!
