After talking to another forum member about getting a roo for my mixed flock, I started wondering what happens when you mix certian breeds of chicken. I have RIR's, BO's, and JG's. What would the offspring look like if I had a BR roo? Are chicken genetics similar to other animals where you get a mix of looks between the two parents, or would you get something completely different? Would the egg production of the offspring still be good?
