I was just looking at a thread on self-sufficiency and it got me thinking about raising meat birds. I've been thinking about doing this when we move to our new place and have much more room for chickens. I'm interested in having a free range flock that we can cull when needed but I'm curious what they'll need in the way of a coop and food. I'll probably lock them in at night but during the day they'll just be out. What are the coop size requirements for free range meat birds? Is it still 4 - 5 sq ft per bird? Also, what feed requirements will free range birds need? I'd like to keep feed costs down as much as possible for this flock. To give you an idea of what our setup will be: We've got 5 acres, about 2.5 acres are cleared, 2.5 are wooded. I'm planning on having 20 to 30 free range birds at any given time and will likely just cull as needed.
