Sadly it's not for MY chickens. My mom moved back to the area a while ago, has 15 acres and she wants chickens. I get to build the coop and live vicariously through her chickens. This is the plan I'm basing mine off of. This one is supposedly 10x10, but I'm making mine 8x16. The coop part will be 8x4, the rest will be the run. Plan to put sand in it. Got most of the frame put together today, just need to pick up the rest of the lumber I need and then assemble some other weekend.
