The coop construction looks great. I don't know what additional securities you have around the property, but I want to make sure that you as well as anyone looking to this as an example in the future are aware: Chicken wire is great for keeping birds in, but not for keeping predators out. Many predators will rip right through chicken wire with their claws or teeth. 1/2" hardware cloth is recommended for smaller predators (fox/raccoon/coyote). I have seen it recommended that the hardware cloth either be sunk 1 foot into the ground, or laid around the pen as a 2 foot skirt in areas with digging predators. Also raccoons can figure out a simple bolt latch fairly quickly so if that is the only line of defense, it may not be adequate. For more information and maybe specifics for your area, I would browse through

I lost 2 ducks to predators early in our stewardship (
