So I agian will be trying To hatch Hungrain yellow chickens ( in fact one year ago to day i got 60 eggs). This strain ( will one of the only strains in the world) is highly in bred. Fertility & hatch rate is low very low. I have also found that a few of the chicks will die. So My question is, How would i be able to bring hatchablty and fertility with out cross breeding? I am thinking line breeding but i am not sure that is the way to go.
