It wouldn't a permanent arrangement but I have a 3'x5'x2.5' tall box covered in 1 inch hex chicken wire that my 4 chicks hang out in during the day and I wonder if eventually I could predator-proof it so they could be in it at night. Until I figure that out though, could I leave a large airline-approved dog carrier inside the tractor so they could go into that at night? The latch requires quite a bit of strength and to be pulled in two directions (you need thumb and a bigger hand than a racoon) to open it. A racoon could reach in if they got past the chicken wire tractor - but I don't think they could get through the plastic dog crate. Has anyone done this?
