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 characteristics have been promoted to an extreme degree. Partly due to the discussion about male offspring ...
The quantity of feed, and the nutritional requirements of the feed, depend on the weight and age of the poultry, their rate of growth, their rate of egg production, the weather (cold or wet weather causes higher energy expenditure), and the amount of nutrition the poultry obtain from foraging. This results in a wide variety of feed formulations.
Sex-links come in several varieties. As hybrids of laying or dual-purpose breeds infused with extra vigor via heterosis, sex-links can be extremely good egg-layers which often produce 300 eggs a year or more depending on the quality of care and feed. The color of their eggs vary according to the mix of breeds, and blue-green eggs are possible.
Improperly stored feed can become compromised and affect egg production, too. “Backyard flock producers don’t necessarily follow lighting programs to support peak egg production,” Anderson said.
The ISA Brown is a crossbreed of chicken, with sex-linked coloration.It is thought to have been the result of a complex series of crosses including but not limited to Rhode Island Reds and Rhode Island Whites, and contains genes from a wide range of breeds, the list of which is a closely guarded secret.

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 ...
Egg producers carefully consider cultural issues, as well as commercial ones, when selecting the breed or breeds of chickens used for production, as egg color varies between breeds. [119] Among producers and breeders, brown eggs often are referred to as "tinted", while the speckled eggs preferred by some consumers often are referred to as being ...
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 ]
