Actually the chickens aren’t a bad idea. My sister and nephew each have chickens they are both in very upscale areas. You just need some land around your house.
Actually chickens are a bad idea unless it’s a commercial venture. The expense, mess, cleanup, upkeep etc isn’t worth it based on the fact eggs are relatively cheap if that’s what ya want.
Ducks, too. (And lots of dogs - I don’t want to think about it.)
