when to put out in the coop???

[momoftwinsinwi]

At what age can I put the chicks out in the coop, I'm afraid after about 3 weeks, they are going to start jumping out of the kiddie pool I have them in, the sides come up about 10" -maybe a foot??? I would hate to start chasing chicks around my messy garage LOL...or should I say my husband's "store all"
