I have a young, small flock of Columbian Wyandottes. They've just started back to laying sporadically this week, and I want to set some eggs to hatch out more to increase my flock size. What problems would I run into keeping the best of the best of the cockerels so that I would have a back up roo incase something (heaven forbid!) to my adult roo? Or, would I be better off to just purchase a decent roo from unrelated bloodlines? I already plan to keep the best pullets from the hatchlings and breed those back to the father.
