My hens are JG, BO, Hubbards, and the roo I am concidering using is a RIR. I am going to try to hatch some eggs and have been checking for signs of fertility every time I crack an egg and it appears that my roo has been doing a good job. The question I pose to anyone with experience in this is if I will end up with layers or fryers? Or if hatchability is compramised because they are mixed breeds. My goal is to have enough girls laying in the spring to justify the cost of becoming a legal seller in Michigan. Opinions?
