One reader asked if he could breed his rooster with the cock ’s offspring , and the short reply is yes , but only in the short term . In stock farming , what we ’d unremarkably call inbreeding is termedlinebreeding . This method acting is how breeder reduce a variety of possible characteristic to produce the very best - attend and -performing breeds and even to make new breeds over time .
However , brusque answers are n’t always the most revealing . Here ’s my long response , which should help resolve a few more of your questions .
Pros Of Linebreeding
Linebreeding is a genetics game , but it ’s what ’s give us our favorite breeds : the Australorp for her prolific orchis laying ; the Orpington for her friendliness ; the Barred Rock for her meat production and dependable laying . Beauty , foraging , meat flavour , and tolerance for restriction , heat and frigid are other characteristics that have been linebred into the strain wimp keepers lie with .
Linebreeding will also help save many of our endangered breeds that were primitively created with linebreeding . These are strain that have since fallen from popularity .
When it come to breeding your own chickens , linebreeding with your very effective stock will preserve their most desirable traits . A favorable and protective rooster is likely to produce more friendly and protective roosters . A honorable forager and authentic bollock layer can produce more of the same .
Cons Of Linebreeding
For linebreeding to assure that offspring will exhibit certain desirable characteristics , it requires that the genetic science miss variety , aka possibilities . While undertake a sure case of comb , feather color or personality trait , linebreeding will reduce the offspring ’s ability to fight disease by copying resistance of the parent , as disease - causing microorganisms evolve in the environment around them .
One disease that can scourge a hatful is avian flu , or razzing flu . When flu hits a mass with genetics that are similar class after year , genetics that have not evolved along with the evolution of disease , a flock can be wipe out . We ’ve seen this with flu and warehouses of egg layer . These birds have been bred for parturiency and prolific egg laying only , and they ’re feed antibiotics because they have little to no defenses of their own . One puff of bird flu — a virus , so antibiotics are ineffective — and the whole building ’s ball layer are destroyed .
When flu attain a backyard flock with diverse genetic science and tidy living conditions , they ’re more potential to survive . Some bird might still be weaker than others and break of the sickness , but this fold has a good fortune of leaving some survivors . come through the unwellness strengthens the potential for disease - fight power of the flock and of the survivors ’ issue . This is development !
Introduce New Stock
When practicing linebreeding , it ’s necessary to acquaint fresh , unrelated reproduction stock every so often to increase the mountain ’s genetic diversity . unexampled blood in the line will strengthen the troop .
Dig A Deeper Gene Pool
The most genetically diverse flock is either motley with different breeds ( although each strain ’s parent could have been relate ) , or the flock consist of chicken so motley between strain that it has no recognizable breeds at all .
Breeding two chickens with the most desirable traits but with the least transmitted similarity will create issue with the strongest potential for survival of the fittest . While you could spawn your chicken with their offspring in the inadequate term , diversity is a must in the long term .
