An ISA Brown chicken at Wylam, England.

From Wikipedia:

The ISA Brown is a crossbreed of chicken, with sex-linked coloration. It is thought to have been the result of a complex series of crosses including but not limited to Rhode Island Reds and Rhode Island Whites, and contains genes from a wide range of breeds, the list of which is a closely guarded secret. It is known for its high egg production of approximately 300 eggs per hen in the first year of laying.
