My kind of set up for my chickens Is kind of free range and kind of not. I have a area fenced off in my backyard that is 36x55 ft, i'm planning on putting a fence so it cuts that space in half, or half as I can get it without blocking my gate, for two separate small flocks, or an integration pen. In front of that main square, to the left, is a smaller square that juts out. that's 11x15 ft. I plan on putting my brooding/sitting hens here to raise chicks away from the flock. I have some basic plans I made in ms paint, really basic as of right now. some of this probably won't make it to the actual finished pen, but it's a start.
