I have 4 chicks that are 2 weeks, 4 chicks that are 3 weeks, and 1 that is almost 4 weeks old. They spent their first few weeks in a dog crate with a heat lamp in my living room. The dust and noise were too much and even though it's the largest dog crate, it seemed too small, and they've been spending the days outside in their coop and run. We have an Eglu with 3 extra run pieces, in a covered terrace. Every night I go out and carry them inside and they are NOT happy about it. They spend the nights huddled near the door to the crate and the heat lamp is in the back of the crate. Since they appear to not need it, I've turned it off the past 2 nights and they don't appear to be cold at all. The outside temp during the day is usually around 98. My house is usually kept at 76 degrees. I don't think there's much chance that the outside temp gets any colder than my living room at night. I know the general rule is not to move them out without heat until 6 weeks but my living room stinks and the whole house has a fine layer of dust on it. I'm having company over tonight and the crate is getting closed up and put away and the room dusted and cleaned. I don't want to bring them back in. Would it really be that big of a deal to start closing them up in the coop at night instead of bringing them back inside? What exactly is the reason for keeping them inside until 6 weeks?
