Let me add that they can also be let out into a 1/3 acre fenced area (where our goats will be when we get them) that the coop and run are already inside. Obviously that will be when we're home to be observing. But days when we'll be gone a lot they'll be in the coop/run area. Maybe I should...
Ok, so- my wonderful brother has volunteered to build my coop on his job site where he has access to left over construction materials and, of course, his crew... must be nice, I know. Gotta love big brothers. I sent him my plans and ideas, and he has thrown in some of his own suggestions...
