Not coop kit-A Shed Kit which is only the galvanized steel (not plastic!) braces. You supply the lumber, insulation, and wire and plans separately. Order 2 or 3 kits so you can have a big run attached and insulated feed/brooder room with sturdy shelves deep enough for incubators, brooder bins, supplements, and testing supplies and on the other wall have metal cans for feed and high nails to hang spare equipment, extension cord and folding stool. Build nests to add on for gathering eggs from the outside (with secure latches, not sliding bolts or springs because raccoons learn to operate them), or buy galvanized metal roll-out nests that can attach to the wall (I use the biggest dog crates for breeding pens for trios and the Premier single roll-out nest is perfect so could work in a little coop too). For runs find 3/4 inch galvanized wire mesh excludes larger rodents (chicken wire will allow rats through and stray dogs can rip it). Definitely add flight net on a sturdy support (chicken wire 1" is ok for that and can support some snow). Add a greenhouse solar automatic vent. Used double-pane windows if you can find them; try to collect them before building the walls so you can frame wide enough. For siding use plywood scraps begged from construction site foremen and seal it or buy vinyl siding remnants to cover it, or buy t&g T111 and seal that. Alternate: call a shed mover (not a vendor) and ask them for a reduced price on a used shed "someday" when they are upgrading someone's, then ready site & wait for a call. Add nests on the side and fresh siding. We got one for $200 delivered and repaired it cheaply. If you get freezes, insulate using recycled styrofoam sheets or shippers broken down to sheets with floor underlayment as paneling over it on the walls; paint with glossy to enable pressure-washing. linoleum roll flooring yes!
