It would be nice to have a few hens around. I wouldn't mind my neighbors having them.
Years ago I lived across town. My neighbor bought chicks at Easter for his kids. He ended up keeping them in his garage at night and during the day let them roam in his yard. Only they came over in my yard. Turned out they all grew into roosters.
Someone turned him in and snitched on him. It wasn't me as I didn't mind. So he had to get rid of his chickens. I don't know what he did with them but one day they were gone.
