[1] [2] Worldwide, around 7 billion male chicks are culled each year in the egg industry. [3] 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 ...
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.
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.
The theory gained steam on Facebook, TikTok and Twitter in recent weeks, with some users reporting that their hens stopped laying eggs and speculating that common chicken feed products were the cause.
The bill, which took effect in recent years, in part banned confinement of egg-laying hens (chickens, turkeys, ducks, geese and guinea fowl) in certain areas with less than 1 square foot of usable ...
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.
More than 40% of the nation's roughly 300 million egg-laying hens are raised in cage-free facilities, but roughly 60% of "bird flu" cases recently detected involved cage-free farms.
