Yes that sounds like what I do. I have been thinking on BUILDing a cage JUST for a brooder but I have several ideas thats why I wanted to see a couple pictures of some that are being used & what the good and bad points are so I can tweek mine
My quail chicks love to run... they are fast.... and to give them places to hide I put in paper towel rolls, and the smaller jiffey pots with a side ripped off for them to hide in.
