My husband and I are building a coop. It's made from an old play structure we've had forever (he actually built it in high school). We're adding a run to the back so the chickens have some dirt to scratch in. Basically, it's like this: the structure is about 6 1/2 feet square (over 6 feet tall as well). It is wooden and very sturdy. There are "windows" (wire-covered openings) on all sides. There's a front door for people or chickens. There' s back door that's 3 feet of wire on the top and open at the bottom into the run. Inside, we have a shelf for roosting with nesting boxes under it. We also will have a roosting pole, a suspended feeder and waterer and plenty of bedding. The floor of this section is wooden slats, so nothing can come from underneath. The run, which is permanently attached, is about 8 feet long, 6 feet wide and 4 feet tall. It's a wooden frame covered in wire. There's wire buried a few inches under ground, too, to keep out predators. The run also has a door so we can get in/let chickens out. We're planning on 2 locks on each door. We live in an area where there aren't many predators - a couple of cats, some predatory birds, maybe a lost raccoon, so I'm not so worried about that. We have little yappy dogs to chase things away as well. So, what haven't we thought about? What do our chickens absolutely need us to change or do before they arrive? I'm thinking this will be an on-going project for quite some time, so "This would be good in the future" and "This is something you HAVE to do NOW" are both welcome! Thanks!
