Is this possible? I have the chance to get my hands on some nice mottled Cochins. I would love to pair them with an extra silkie roo I have and see what I get. If I wanted to start a project to make some nice Mottled silkies what color of silkie should I breed the Mottled cochins with? Would the OS from these be consider F1? Then how should I go about picking the best ones to breed F2? and what should I breed them back to? Another silkie or what color? Thanks to all those Gene experts who answer!
