After a few years of cursing the "useful" junk left by the previous owner of the house, I finally found a use for the old fridge and oven racks: these can serve as window gratings on the chicken coop! Sturdier than hardware cloth and a far sight cheaper, and still weasel proof--I think. They are also the perfect size to cover the brooder box. The commercial sized baking sheets that the other owner also left, which are too unpleasant to use for baking and too big for the oven anyhow, will be poop trays under the roost. If there are old fridges or stoves lurking around at your local dump, why not reclaim some useful grille material?
