Why don't you butcher your extra roosters, Poltergeist? I do. Meat is fine.
I just set free 23 guineas I raised. Bought them at 4 weeks old at our monthly fowl auction, pd $3 a piece. Different colors. Kept them indoors in a brooder, feed is game bird starter (like you feed turkey babies). We have 23 acres, and I have no clue where they are sleeping. Have 2 large barns, an open barn, and a roundtop, so they're sleeping somewhere. They took off one morning to the neighbor's farm and made a bunch of noise in their driveway, then came back home. I love guineas because they keep the tick and chigger population down considerably. Still have to put food and water out for them, but will probably not need to when the bug population starts up. They are noisy, but I don't mind. They move in a herd, and are very entertaining. They come running in the morning to follow my feed wagon when I go out to do animal chores, knowing I'm going to dump chicken scratch out for them. They had to stay in our milkhouse for months before I released them because our weather was so bad. Just above freezing temps at night now, so it's fine. We lost 50 of them the year prior...neighbor's dog mostly, and a few to a raccoon.
