Chickens farmed primarily for eggs are called layer hens. The UK alone consumes more than 34 million eggs per day. [ 84 ] Hens of some breeds can produce over 300 eggs per year; the highest authenticated rate of egg laying is 371 eggs in 364 days. [ 85 ]
Floor space ranges upwards from 300 cm 2 per hen. EU standards in 2003 called for at least 550 cm 2 per hen.

Any breed may be used for general agricultural purposes, and all breeds are shown to some degree. But each chicken breed is known for a primary use.
As is the case with chickens, various breeds have been developed, selected for egg-laying ability, fast growth, and a well-covered carcase. The most common commercial breed in the United Kingdom and the United States is the Pekin duck, which can lay 200 eggs a year and can reach a weight of 3.5 kg (7 lb 11 oz) in 44 days. [34]
