Feeding It is important for the health of your chickens to provide a good diet. It should be said, that commercial enterprises have turned Leghorns into laying machines, and production Rhode Island Reds are quite commonly used in "egg factories," so even non-sex-linked male chicks can suffer the same horrendous fates. So again, thank you so much for making my dreams come true! Isolated the bad hen in a pet cage for three days and let her watch the other hens free-range. It works best, of course, if you start with very productive breeds. The commercial strains have been developed using decades of selective breeding for highly productive hens, and the breeding occurs under highly controlled conditions, so your attempts may not come close to producing similar results. Both are mostly black, but males will have a white spot on the head.

Unlike the Red Sex-Links, there is a more subtle difference between the sexes at hatching. Although experiments with sex-linked inheritance in chickens have been conducted for more than years, the development of commercial sex-linked hybrid strains started largely after World War II. The male chicks could be disposed of quickly, since there were no longer of use commercially as meat birds, since they would take twice as much time or longer as Cornish-Rock crosses to develop full size and they never would develop as much white meat. In poultry, the males carry two full genes for color and the females carry the sex-determining gene and one gene for color. The Way Things Used to Be Once upon a time, when chickens were mostly raised on small farms and in back yards, folks didn't try to specialize in types of chickens. These two crosses are simply called Red Sexlinks. For many years New Hampshire Reds were crossed with Barred Plymouth Rocks — producing fast-growing, meaty and tasty market poultry.

Black and Red Breed Details: With crossing different breeds, as well, you eliminate the problems associated with inbreeding. Popular names under which they are marketed include: Red Sex-Links What is known as the "silver trait" is found in hens of many, but not all, white-feathered varieties or breeds and some with silver lacing.
A word about sex-links
Description: The idea of purity in a genetic population has old roots, but was not widely applied to poultry until the s. In addition, there are too many sex-link strains and varieties to make their inclusion practical, and for many of those strains the only information about them are claims about how very productive they are.
