I have 3 standard cochins- Black 1 roo - 2 pullets-- Could anyone please explain to me ---- In very simple terms please How can I get some blue cochins. I mean what color do I need to mix to produce blues . My roo has a few red streaks in his neck so he may have some Partridge? in him. I also love the blue langshans. I know I would have to at least get one Blue or Splash - right?
