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 ...
Clark Gable, in the 1945 film Adventure, hypnotizes a rooster while he and Greer Garson try to lure chickens from behind the bush by using the rooster as bait. Werner Herzog has included chicken hypnotism in several films, [ 12 ] including the 1968 Signs of Life , which features a scene in which a chicken is hypnotized by a line drawn by chalk ...
A feral rooster on the island of Kauai A family of feral chickens, Key West, Florida. Feral chickens are derived from domestic chickens (Gallus domesticus) who have returned to the wild. 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]
Schjelderup-Ebbe noted in his 1924 German-language article that "defense and aggression in the hen is accomplished with the beak". [5] This emphasis on pecking led many subsequent studies on fowl behaviour to use it as a primary observation, however, it has been noted that roosters tend to leap and use their claws in conflicts.

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]
To understand how hens visibly express emotion, researchers spent four weeks on a French farm observing 17 hens of two different breeds, Bertin said, filming their routine behaviors and their ...
Fewer chickens means fewer eggs, and fewer eggs means pricier eggs — especially as demand rises over the holiday season (all that baking) and in the lead-up to Easter (all that painting).
Most chickens are raised for food, providing meat and eggs; others are kept as pets [1] or for cockfighting. Chickens are common and widespread domestic animals, with a total population of 26.5 billion as of 2023, and an annual production of more than 50 billion birds. A hen bred for laying can produce over 300 eggs per year.
