Hi, I have 9 Delaware birds (8 hens+1roo) purchased from a local farm store. They buy their chicks from a large commercial hatchery in New Mexico. Anyhow, my goal is to breed the birds to replace my flock over time. My understanding is that these chicks are really not related because of the size of operation. Are chicks generally related when they come from commercial hatcheries? If not, and I breed a flock of offspring, I have to end it there unless I fertilize the eggs with a different roo, correct? Thanks folks!
