Some of the Amish farms in Lancaster County, PA have egg-laying chickens for free. You have to capture them in the barns, slaughter them, unpluck their feathers, and clean them up yourself though. Plus, the chicken meat is quite hard to bite. People have to boil them for hours and hours to soften up the meat.
Roosters and hens--every one must be slaughtered for the new flocks to lay eggs in the same barns.
