When seeking chickens, beware of one breed in China: S: 田鸡; T: 田雞 (tián jī, literally 'field chicken').
Tasty as these are, they are not what you may want. 'Field Chickens' are the Chinese edible frog Hoplobatracus rugulosos.
These are sold live in many supermarkets or wet markets but can also be bought post mortem and skinned.

Also, 鸡 (jī, literally 'chicken') is slang for a prostitute. No image for that breed.
