I'm trying to get started breeding my chickens but I want to stat with decant blood. All I have are chickens from hatcheries and some from tractor supply. I know I can't start with some champion bloodline but I do what to have something haft way decent. I'm going for a self sustaining flock should I try and find some heritage breed roosters some where? Or do you think I can just go with what I have? Any thoughts or experience would be appreciated!
