I picked this old crate/chest up at a junk shop for $20. When I saw it I knew it would be perfect. It is well built, thick and heavy. And I knew the middle lid panel could be pried up. I cut and fit a welded wire piece over the opening and stapled it down. Add chickens and heat. I think it is predator proof. My chicks are in it on my side porch with a heat lamp. I also took this wooden crate and lined the open sides with welded hardware cloth. I used an old picture frame lined with the same wire to make a top. This one will go upstairs if or when any of those goose eggs hatch. I like using things I already have on hand but when I saw the chest thing I had to have it. I am glad I bought it or I would be kicking myself everywhich way right now.
