Birds will be supplemented with kitchen scraps (from a small family) and feed as needed. I read some interesting things about placing a hay bale or two in the area to get bugs for them. Don't want to kill all the grass, and want the chickens as reasonably stress fee and healthy as possible. Anticipate starting three birds, small coop, protected area, and going from there. Want them and their area to be robust, but land is finite.
