They are in my area of the US (well, backyard chickens and ducks in general are very popular). A lot of rescue chickens around here are unwanted roosters as a lot of towns ban people from keeping roosters. Some people around here have full on chicken bachelor pads. As far as the fanciness of their coop, there are some insane chicken mansions out there. Usually it's people with carpentry skills building elaborate coops for themselves but I've heard of wealthy people dropping $10k+ for a custom coop. I keep a few hens and it's a fun hobby.Are rescue chickens not a thing in the US? They very much are in the UK. The chickens are rescued from battery farms which usually have the chickens in appalling conditions.
