My hens are 2 Easter Eggers, 1 Wyandotte, 1 Black Sexlink, and 1 Buff Orpington. If i Breed to a RIR what kind of offspring will I get and what will the egg colors be? What would you suggest in terms of a roo to breed with my girls? What other girls should I get to get a more colorful egg basket? Thank you for all your help.
