Chickens in multiple-occupancy battery cages. Battery cages are a housing system used by factory farms for various animal production methods, but primarily for egg-laying hens. The name arises from the arrangement of rows and columns of identical cages connected, in a unit, as in an artillery battery. Although the term is usually applied to ...
On average, a chicken lays one egg a day for a number of days (a "clutch"), then does not lay for one or more days, then lays another clutch. Originally, the hen presumably laid one clutch, became broody, and incubated the eggs. Selective breeding over the centuries has produced hens that lay more eggs than they can hatch. Some of this progress ...
A free range pastured chicken system. Pastured poultry also known as pasture-raised poultry or pasture raised eggs is a sustainable agriculture technique that calls for the raising of laying chickens, meat chickens (broilers), guinea fowl, and/or turkeys on pasture, as opposed to indoor confinement like in battery cage hens or in some cage-free and 'free range' setups with limited "access ...
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 ...
Organic egg production is the production of eggs through organic means. In this process, the poultry are fed organic feed. In this process, the poultry are fed organic feed. According to the United States Department of Agriculture, organic means that the laying hens must have access to the outdoors and cannot be raised in cages. [ 1 ]
A furnished cage, sometimes called enriched cage, colony cage or modified cage, is a type of cage used in poultry farming for egg laying hens.Furnished cages have been designed to overcome some of the welfare concerns of battery cages (also called 'conventional' or 'traditional cages') whilst retaining their economic and husbandry advantages, and also provide some of the welfare advantages ...
A dual-purpose chicken is a type of chicken that may be used in the production of both eggs and meat. [42] In the past, many chicken breeds were selected for both functions. However, since the advent of laying and meat hybrids, industrial chicken breeding has made a sharp distinction between chickens with either function, [ 43 ] so that certain ...
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. In free-range systems, hens are housed to ...
