That would be line breeding but we are still pen breeding correct? That is where I am foggy.
@marchick your breeding program is more advenced than mine and @kfelton0002 .
your chooks proven to have a correct Sex linked genes Z and W , it is a reason why your this year hatch are correct on they conformation and body colour ,tail and comb .so you line is almost done , need to be maitain now not to be bred .technial tern
@kfelton0002 here line has a proper W sex linked but missing a good Z chromozome . correct cockerel . so she is a second .
I m the last .I just a young improven stock . just figuring out who is who and what pakage they bringing in with them . so I m far away to start a line .I m just teat mating and studying my chooks make up .
