I have 10 almost 6 week old chicks that I started putting out in a chick coop 2 nights ago. 3 Brahma, 3 faverolles, and 4 bantams one of which is a frizzle. They are on gravel and have 2 chick brooder plates. I still have their cage set up indoors. The outside cage is open on 3 sides but I can put some wind blocks up.
