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 chicken farmers who are eventually faced with the decision to either slaughter older layers or keep them as non-producing pets.
Forced molting typically involves the removal of food and/or water from poultry for an extended period of time to reinvigorate egg-laying. Forced molting, sometimes known as induced molting, is the practice by some poultry industries of artificially provoking a flock to molt simultaneously, typically by withdrawing food for 7–14 days and sometimes also withdrawing water for an extended period.
The UK alone consumes more than 34 million eggs per day. [85] Hens of some breeds can produce over 300 eggs per year; the highest authenticated rate of egg laying is 371 eggs in 364 days. [86] After 12 months of laying, the commercial hen's egg-laying ability declines to the point where the flock is commercially unviable.
Norway: In May 2023, Jæren-based company Steinsland & Co and Nortura, representing two-thirds of the Norwegian laying hen market, installed the first Seleggt in-ovo sexing technology in the country in order to sort out fertilised male eggs before the 13th day of incubation, with the aim of gradually phasing out all hatched chick culling in the ...

They are not a modern dual purpose breed but do lay a lot of medium-sized white to pale tan eggs, and often lay over a long lifetime and during winter months. Some hens in every flock will go broody and be excellent mothers. Icelandics are medium-sized and have a small carcass weight (about 2.5 pounds for a five month old cockerel).
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. [28] One problem facing prairie-chickens is competition with the ring-necked pheasants. Pheasants lay ...
The first amniote egg – that is, a hard-shelled egg that could be laid on land, rather than remaining in water like the eggs of fish or amphibians – appeared around 312 million years ago. [6] In contrast, chickens are domesticated descendants of red junglefowl and probably arose little more than eight thousand years ago, at most. [7]
