What's the biggest size difference you have seen between parents of chicks? I understand that the mechanics of mating don't work out if there is to great a difference. Has anyone every artificially inseminated a LF hen with a bantam roo? For sake of argument, what would happen if a Jersey Giant were inseminated with a Serama? Could the chicks hatch? I should be getting some chocolate Seramas soon, and I'm curious about spreading the chocolate gene into LF birds.
