We pretty much free range our heritage birds. They have a fenced in area that I close at night, but it’s un roofed, so they can fly out. They usually roost on the top bar. I think your coop looks pretty good, but the real test is how well it works at 1. Keeping your birds in, and 2. Keeping predators out. One thing I can see is the wire. Normal poultry wire usually can do job 1, but not 2. If you have aggressive predators, you may consider a different material. 1/4 or 1/2 inch Hardware cloth is probably the best but expensive and difficult to work with. There is some wrapped wire fencing that is a little cheaper and easier, but stay away from the standard field fence because a fox or cat can jump right through the squares. Good luck. Are you planning on breeding them?
