I just moved my 5, 7.5 week old chicks outside into their run with the hutch. They have no netting overhead but they do have a crawl space that a hawk cant get into. I am pretty sure the hutch is predator proof. I will put a sheet over it tonight to make sure coons or weasels don't get in. My grandma also got me some spray to put around the coop and the animals don't like it. I already had to get rid of a snake that could be a potential threat to my chicks after I read the post by the lady whos chicks got eaten. Very nervous. they should be fine though.
