Description. Although daily egg production starts to tail off after one year old, it may continue until 5–7 years old. Older hens gradually produce fewer eggs, and the eggs are usually larger. [ 1] Since the average lifespan of a pet layer hen is 8–15 years, [ 2] henopause has received attention as a potential problem for backyard or urban ...
Nesting Box Hens crave privacy and darkness when laying eggs, so plan for at least one nesting box for every four or five hens. A box that measures 14"W-by-14"H x 12"D will give even a big gal ...
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. In Europe, they are generally butchered after a single season. The laying period begins when the hen is about 18–20 weeks old (depending on breed and season).
Chickens are common and widespread domestic animals, with a total population of 26.5 billion as of 2023, and an annual production of more than 50 billion birds.

A study of female greater prairie-chickens in Kansas found that their survival rates were 1.6 to 2.0 times higher during the non-breeding season compared to the breeding season; this was due to heavy predation during nesting and brood-rearing. [16] One problem facing prairie-chickens is competition with the ring-necked pheasants. Pheasants lay ...
An egg incubator. Because hens stop laying when they become broody, commercial poultry breeders perceive broodiness as an impediment to egg and poultry meat production. [8] With domestication, it has become more profitable to incubate eggs artificially, while keeping hens in full egg production.
