I have 6 Red star chickens that I raised from 12 weeks and are almost a year old. I have never had baby chicks that are only a week or so old. I brought the two chicks home yesterday and set them up in a little bird cage but did not realize I needed a lamp because the person I asked questions at the store new nothing and neither did anyone else. Did I mentioned I didn't plan on going there for more chikens LOL. So I keep my house around 68degrees at night and they slept huddled together in the cedar flakes and were very quite, did not seem to be shaking or anything. This morning they seemed fine, so my questions is since they are inside birds right now do I even need to waste money on a lamp since I have been reading that most folks turn the light of at 3-4 weeks? I also have them in front of the window with the sun during the day. Thanks a bunch for any advice.
