Corn-fed free range chicken. In France, there is a big distinction made between "poulet fermier" and "normal chicken" or "industrial chicken". "Poulet fermier" can mean two things: either the bird is a "open air chicken", which means he has spent his life in a large open air area and has been fed grain and milk, and/or he is a "free range chicken", the highest quality chicken, and was able to freely run and being fed grain and milk. Yellow chickens are corn fed, while whiter chickens are wheat fed.
