A friend/neighbor has a large flock (to me anyhow, 250+ birds). They sell the eggs at our local health food store. Anyway, they want to cull some of their older birds but say they can't do it themselves so would like us to do it. I was wondering if we could grind the breasts and maybe the thighs and use the meat that way? I know they won't be fit to eat otherwise. Was also wondering if canning them would tenderize them? Anyone with any experience in this area?
