I'd love to keep a few chickens in the back yard for the eggs but despite being on the outer fringe of a small, somewhat rural town we're not zoned agricultural. I seriously doubt the city'd even care as long as we kept it to 2 or 3 hens and stayed in our lane, but we have an abundance of feral cats in the immediate neighborhood too, some of them rather large. There's also coyotes out in the woods.
