Another study found that brown-egg laying hens are more likely to engage in feather pecking than white-egg laying hens. [1] The genetics of poultry will not guarantee a bird will engage in cannibalism, but the genes a bird possesses play a part in the degree of aggressiveness a bird could engage in feather pecking and increases their risk ...
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]
Red shaver hens can lay from 305 to 315 eggs a year, [3] and are reported to be prolific producers of large brown eggs. One four-year-old Red Shaver chicken in Ottawa was credited with laying an egg with a mass of 143 grams, which is almost three times the size of a standard medium egg (Typically a medium egg is 49 g, a jumbo egg is 70 g).
[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 ...
Like the red junglefowl (the closest wild relative of domestic chickens), feral chickens will roost in bushes in order to avoid predators at night. [1] Feral chickens typically form social groups composed of a dominant cockerel, several hens, and subordinate cocks. Sometimes the dominant cockerel is designated by a fight between cocks. [2]
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.

Egg laying hens: Cage-free egg production includes barn, free-range and organic systems. The UK is the largest free-range egg producer in the Europe. [ 21 ] Free-range systems are the most popular of the non-cage alternatives, accounting for around 57% of all eggs, compared to 2% in barns and 2% organic.
