Will this work as a brooder for chicks 3-5 weeks old Untill I can move them outside? I have 10 babies right now. I'm trying not to spend too much money on this so I can put that money into the coop. There is a screen on top of storage cubes hinged together with zip ties, a underbed storage tub all on a table. I thought that having the thing raised would keep drafts from under the garage doors away. Does this look OK? Any suggestions? Thanks!
