if i buy chicks from a hatchery and breek them is it inbreeding?

Most likely, no, but there is no way to totally know the parentage of a mixed batch of hatchery chicks. It's more likely there would be some 'linebreeding.'

Inbreeding is specifically brother/sister, father/daughter, mother/son. Linebreeding is half brother to half sister (different fathers/mothers); father to granddaughter; and 'cousins,' for examples.

Inbreeding/linebreeding in chickens is not inherently a problem.
 
it won't be a problem for the first two generations or so.... but if they are from a hatchery, it's a toss up whether or not they are related... I'd think most likely not if it's a huge hatchery... and if they are related, it's most likely by father only.... I'm pretty sure you'll be ok... if you're really worried, you could always buy your birds from different hatcheries.. ??
 
it will only affect the chicks if you keep doing it for more than one or two generations.... say if you breed two that happen to be related, and then out of the chicks that hatch, you breed those together and so on. but the first babies born to possibly related chickens will be fine.
 
You could ask the hatchery about how many sources they have etc. Even with "inbreeding" if you select choice birds to breed and they have nice offspring, you done good!
Most purebred animals have had to be bred close in order to "lock in" the desired traits.
Close breeding locks in both good and bad traits.
So if you breed good x good and get good you may have established a new bloodline and your birds will breed true!
 
It can take up to several generations of inbreeding related birds to even begin to show any negative effect. Chickens are MUCH different from mammals.

After five generations things like lower fertility start to crop up and then you outcross. Or just do it after every three or four generations and don't worry about it.

Initially tight inbreeding can really help a breeding program if it has goals.

good info! I love genetics -- what is a good source to study this with birds. i do mammals, but not birds (yet

The eggs come from thousands of breeder chickens, all gather within a week. So odd most will be from different birds..

They set thousands of eggs per week.
