Yeah, we have a park with chickens, ducks, geese, swans, marsh birds, etc. The park was used as a "dumping ground" for unwanted pets. It's now forbidden to do that. Most of the dogs and cats are easily found and taken shelters. The easter chickens and roosters were left to range freely. I would assume there are also rabbits, although I've never seen any. I'd estimate there are 200+/- chickens. The park is about 5000 acres and used to be a horse race course until the mid 1960's.
