Hi, I have 9 chicks hatched the day before Valentines day so they are 4 weeks tomorrow. Not fully feathered of course and I still have them under the heat lamp. They are currently in my house in a baby pool with gates around the sides to keep them in. I'm in VA and temps have dropped for this week but range from 30s to 60's. When is it possible to move them to our attached garage with the heat lamp? These are our 2nd set of chicks but the last ones we got it was summer and so hot that we moved them out early and they did fine. I'm ok keeping them in but obviously the bigger they get the more they smell and the dust is annoying to keep up with. We also have one chick developing slower than the rest who doesn't have very much feathers yet so we may have to keep them in longer for him/her.
