Because male chickens do not lay eggs and only those in breeding programmes are required to fertilise eggs, they are considered redundant to the egg-laying industry and are usually killed shortly after being sexed, which occurs just days after they are conceived or after they hatch. [3]
The UK alone consumes more than 34 million eggs per day. [84] Hens of some breeds can produce over 300 eggs per year; the highest authenticated rate of egg laying is 371 eggs in 364 days. [85] After 12 months of laying, the commercial hen's egg-laying ability declines to the point where the flock is commercially unviable.
A common practice among hatcheries for egg-laying hens is the culling of newly hatched male chicks since they do not lay eggs and do not grow fast enough to be profitable for meat. There are plans to more ethically destroy the eggs before the chicks are hatched, using "in-ovo" sex determination.
A yolkless egg is most often a pullet's first egg, produced before her laying mechanism is fully ready. In a mature hen, a yolkless egg is unlikely, but can occur if a bit of reproductive tissue breaks away, stimulating the egg-producing glands to treat it as a yolk and wrap it in albumen, membranes and a shell as it travels through the egg tube.
Naked Neck chickens. Despite its highly unusual appearance, the breed is not particularly known as an exhibition bird, and is a dual-purpose utility chicken. They lay a respectable number of light brown eggs, and are considered desirable for meat production because they need less plucking and they have a meaty body.
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 plenty of room.
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 farm currently produces about 350 brown eggs daily but expects to bump that up to over 1,000 brown eggs a day after receiving a delivery of more than 700 pullets (or young hens) on this month ...
