In Key West, Florida they are feral, protected, and all over the place! They are the descendants of the Cubalaya and domestic chickens. The Cubalaya chicken started out as some varieties of Filipino fowls from Spain who were cross bred with chickens of European origin for size and aggressiveness for cockfighting. When Cubans began to move to Key West in the 1860’s they brought their chickens with them – as well as cockfighting. When cockfighting was outlawed in the 1970’s, the chickens were booted out to the streets; left to fend for themselves.
It would appear they are embraced by the community in some ways although I wonder if a few haven’t mysteriously made it into a stock pot somewhere 😉
