Hens used for egg production are typically confined in systems housing tens of thousands of birds per building.
Conventional “battery cage” systems give each hen roughly 67 square inches of space — too small to perch, dust bathe, or spread wings.
Beak trimming is performed to reduce injuries from stress-induced pecking.
Air quality often exceeds ammonia concentrations of 25 ppm, causing respiratory and eye issues.
Mortality rates of 5–10% per flock cycle are considered standard operating loss.
Male chicks: Culled immediately after hatching because they cannot lay eggs and are not profitable for meat. Most are killed through maceration or gassing. Parent birds: Breeder hens and roosters, who produce fertile eggs for layer chicks, are confined under controlled lighting to manipulate reproduction. These birds experience skeletal and reproductive strain and are killed when fertility declines.
When Egg Production Slows
After 12–14 months, egg output declines. Hens are labeled “spent.”
Most processing plants do not accept spent hens due to low meat yield and fragile bones.
Induced molting is used to extend egg production: historically via complete feed withdrawal (10–14 days, 25–35% body-weight loss), now sometimes via restricted feeding and light manipulation.
Parent birds follow the same pattern: bred for high yield, replaced when fertility declines.
“Cage-Free” and “Free-Range” Systems
“Cage-free” hens are housed indoors with minimal space (around 1 sq ft per bird), still deprived of natural behaviors.
“Free-range” hens may have outdoor access, but crowding, selective breeding, and lack of shelter limit use.
Mortality rates can equal or exceed caged systems.
Induced molting and end-of-lay depopulation remain standard.
Small and Backyard Flocks
Most chicks sold to backyard keepers originate from the same commercial hatcheries that supply industrial farms.
“Unsexed” orders result in roughly 50% male chicks, most of which are later killed or abandoned.
Parent breeder birds are under the same reproductive pressures as large-scale operations.
Manure from large egg operations contributes to ammonia and nitrate pollution in air and water.
Roughly 90 million spent hens are killed annually in the U.S., mostly for pet food or rendering. Source: ConsiderVeganism.com data -- https://dev.considerveganism.com/data/eggs/
Summary
Egg production depends on intensive breeding, culling of males, confinement of females, and slaughter when productivity declines.
Welfare standards may vary, but the core model is built around economic utility.
Reducing or eliminating demand for eggs is the only way to meaningfully reduce suffering and mortality.
