Broilers bred for fast growth have a high rate of developing leg deformities because their large breast muscles cause distortions on their developing legs and pelvis, leading to them often being unable to support their body weight. In cases where the chickens become crippled and can no longer walk, farmers have to go in and pull them out.
Intensive animal farming, industrial livestock production, and macro-farms, [1] also known as factory farming, [2] is a type of intensive agriculture, specifically an approach to animal husbandry designed to maximize production while minimizing costs. [3]
The prevalence of chickens is due to almost the entire chicken being edible, and the ease of raising them. The chicken domesticated for its meat are broilers and for its eggs are layers. Chicken as a meat has been depicted in Babylonian carvings from around 600 BC. [2] Chicken was one of the most common meats available in the Middle Ages.
Owing to the relative ease and low cost of raising chickens—in comparison to mammals such as cattle or hogs—chicken meat (commonly called just "chicken") and chicken eggs have become prevalent in numerous cuisines. Chicken can be prepared in a vast range of ways, including baking, grilling, barbecuing, frying, boiling, and roasting.
Broiler breeder farms raise parent stock which produce fertilized eggs. A broiler hatching egg is never sold at stores and is not meant for human consumption. [9] The males and females are separate genetic lines or breeds, so that each line can be selected for optimal traits for productivity in either females or males, rather than a single line in which a compromise is reached between female ...
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.
Rapid growth can lead to metabolic disorders such as sudden death syndrome and ascites. [2] Breeding for increased breast muscle affects the way chickens walk and puts additional stresses on their hips and legs. [14] There is a high frequency of skeletal problems in broilers, mainly in the locomotory system. [2]
Urban keeping of chickens as pets, for eggs, meat, or for eating pests is popular in urban and suburban areas.Some people sell the eggs for side income..
