line breeding / inbreeding / crossbreeding

[mons537]

this will read like a statement but I’m just looking for input
Breed Male to Female then Male back to daughter and or hen back to son - keep records - mark your fowl - cull all defects - this is an example of line breeding

Brother Sister matings to set the trait but you must cull ruthlessly - this would be inbreeding although linebreeding is also a form of inbreeding

Taking totally different types of chickens and mating them would be crossbreeding or different strains of the same type may also be considered crossbreeding - this method may produce birds that are better for what they are to be used for than the parents - hybrid vigor

I see that you have made posts in New Members Introductions before. This is the best forum to post - https://www.backyardchickens.com/forums/general-breed-discussions-faq.14/

Don't get outcrossing confused with crossbreeding. Below are some terms I've posted on another forum...they don't allow links on this one to the others.

Terminology
These breeding terminology definitions are based on definitions from "Start Where You Are With What You Have," by Ralph Sturgeon; the Merriam-Webster dictionary; The Poultry Consultancy and other sources.
Breed - birds that meet a written "Standard" description. Often called a recognized or accepted breed.
Purebred - a breed that shares the same genetic makeup, although it would be next to impossible to be "pure" (homozygous) for every trait.
Standard bred - birds that are bred to a "Standard", but not necessarily claimed to be "purebred".
Pedigree - birds with a recorded linage over several generations are considered pedigreed. This is mainly used in commercial hybrid flocks.
Variety - generally relates to the color and pattern of a birds feathers. There can be many varieties within a breed.
Strain or Line - birds of a certain breed and variety that aren't closely related may be of different strains or lines.
Outcrossing - crossing (mating) different strains/lines of a particular breed.
Crossbreeding - "mating two...individuals from (two) totally different breeds".
Mixed breed - when at least one parent bird is not a recognized breed. Several, often unknown, breeds may be involved.

Inbreed & Linebreed

Inbreeding is "the controlled mating of brother to sister, mother to son, father to daughter" to preserve and fix desirable traits & eliminate unfavorable ones. Inbreeding could be viewed as the strictest form of Linebreeding.
Linebreeding is the tool most often used by breeders. Linebreeding is mating "first cousins, nieces with uncles, grandparents with grandchildren and so on" within a line or stain. Keep in mind definitions may vary and even though Inbreeding can be seen as close Linebreeding generally think of Linebreeding as somewhere between Inbreeding and Outcrossing.
