I have been thinking on this subject as well. If our economy was to crash tomorrow, my chicken flock my be the one thing that keeps my family alive. I have a BO roo, BO hen, SLW hen, and a RIR hen. I have been thinking about adding some white egg layers to the mix (perhaps SSH) but I am conserned about non broodiness dominating future generations. If the dont go broody the line will die out. Any thoughts?
