I'm building a coop for our new chicks (got them yesterday!) from materials that I found yesterday at the art museum. They put out the old art shipping crates and various other installation materials when they're done with them. Here's what I got: Dimensions are 86x45x30 inches. It has a removable lid and is made of plywood, 2x4s and 1x4s. It is lined on the inside with Tyvek. and this: It is 8 feet long, 3 feet square with a 15" rise for the roof section. Fully welded steel. So my thought is to cut the crate in half and make more of a true box with it. I would leave the top open and then use the lid to make a slanted, vented roof. We live in AZ, so ventilation is more important to me than anything else. I would also cut a couple of windows and an access door for cleanout, as well as adding an external nesting box. We would raise it about 2' off the ground. The dimensions would be 60x45x43" when complete. If I use this box, raised, and attach the long metal framing to it, enclosing the framing and the underside of the coop with wire, would that be enough room for 4-6 chickens? The box interior is about 18 sf and the run is 42 sf. I want to keep them in the run until I know that my dogs aren't a risk to their well being. Thanks so much for any suggestions or feedback.
