How cold is it where you are? Do you already have chickens and/ or a coop?
Mine are 4 weeks. They were inside for 2 weeks and are now in a larger, covered brooder in the garage. 2 weeks indoors was really pushing it for us with 17 chicks. We have to build a coop, but if we had a coop that is where they would be going soon, but it’s still fairly cold at night here). We have a barn building they can be in while we build, but we’ve found evidence of mice and rats (but seems to be an old/past problem that previous owners dealt with) so we are baiting and cleaning the barn while there are no animals of ours in it.

You'll need that coop sooner than you think.
