Mortalities, due mainly to cannibalism, can be up to 15% in egg-laying flocks housed in aviaries, [11] straw yards, [12] and free-range systems. [13] Because egg-laying strains of chickens can be kept in smaller group sizes in cage systems, cannibalism is reduced, [ 10 ] leading to a lowered trend in mortality as compared to non-cage systems.
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.
About five hours of video showed thousands of hens in cages, birds trapped between cage wire unable to access food or water, and dead animals rotting next to other birds still laying eggs for human consumption. [4] MFA used the footage to discredit a new Animal Care Certified label which advertised that hens were raised humanely. [5]
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.
CLAIM: Chicken feed companies have altered their products to stop backyard hens from laying eggs and drive up demand for commercial eggs. The theory gained steam on Facebook, TikTok and Twitter in ...
Fitting pin-less blinders to laying hens leads to reduced activity, increased resting, adjustment problems in feeding, stereotypic head shaking and protracted displacement neck preening for a month after fitting. [3] In another study on laying hens, mortality was greater among hens wearing blinders compared to hens that had been beak-trimmed. [5]
The same article offers this bit of advice, "Whether you feed your chickens scrambled eggs, or hard-boiled eggs, make sure that you save the eggshells, wash them, dry them out, grind them up and ...
The causes and development of vent pecking are multifarious. Risk factors that have been identified as increasing vent pecking include dim lights placed in nest boxes to encourage hens to use the boxes, the diet being changed more than three times during the egg laying period, the use of bell drinkers, and the hens beginning to lay earlier than 20 weeks of age.
