Diseases can be avoided with proper maintenance of the feed and feeder. A feeder is the device that supplies the feed to the poultry. [8] For privately raised chickens, or chickens as pets, feed can be delivered through jar, trough or tube feeders. The use of poultry feed can also be supplemented with food found through foraging.

Few veal and pig factory farm operations exist in California, so Proposition 2 mostly affects farmers who raise California's 15 million egg-laying hens. [1] In 2010 the California legislature passed AB 1437, which required shell eggs sold in the state to meet the same requirements. Both Proposition 2 and AB 1437 went into effect in 2015.

In 1900, average egg production was 83 eggs per hen per year. In 2000, it was well over 300. In the United States, laying hens are butchered after their second egg laying season.

The RSPCA "Welfare standards for laying hens and pullets" indicates that the stocking rate must not exceed 1,000 birds per hectare (10 m 2 per hen) of range available and a minimum area of overhead shade/shelter of 8 m 2 per 1,000 hens must be provided. Free-range farming of egg-laying hens is increasing its share of the market.
