In 2011, Washington passed legislation that banned the use of battery cages by 2024, entailing that indoor or outdoor enclosures must provide hens with unrestricted access to roam freely (with the exception of exterior walls to keep the flock inside), enrichments that allow them to exhibit natural behaviors including, at a minimum, scratch areas, perches, nest boxes, and dust bathing areas and farm employees must be able to provide care while standing somewhere within the hens' usable floor space. Any operation violating this law is guilty of a misdemeanor, resulting in a maximum fine of $1,000 and/or up to 90 days in jail. A second or subsequent violation is a gross misdemeanor, resulting in a maximum $5,000 fine and up to 364 days in jail. 

In 2019, Washington expanded upon these restrictions by passing legislation that bans the in-state sale of eggs from hens raised in battery cages by the same deadline as the original law. According to the expanded law, “​​no person shall buy, sell, or transport, or offer to buy or sell, or offer or receive for transportation, in intrastate commerce any egg or egg product that was not produced in compliance with the standards required by [the earlier legislation].”
