Who knew Runner ducks could be so complicated? Indian Runner vs. Runner, Blue vs. Cumberland Blue, etc. A friend of mine got ten little Blue Runner ducklings and they are coming to live at my house. Are they technically Cumberland Blue? Is that the technical color and in the US we have to make everything different from the UK so we just call them Blue instead? (Don't get me started on breed/species standards between the US and Europe as a whole...lol) Am I correct that the blue gene in ducks is similar to the blue gene in chickens. A mating of Blue x Blue should result in 25% Black, 50% Blue, and 25% Silver (which is like Splash in chickens)? It has been well over fifteen years since I've had Runners. Anything special I need to remember about them? I have some young Chocolate Muscovy currently. I know Mallard derivative and Muscovies can hybridize. Has anyone ever had an issue with a large breed like the Muscovy attempting to breed with something small like the Runners? Or vice versa? If so I'll pen them separately once they are old enough to breed. They are supposed to be a month old now, so I'm sure they are in the horribly awkward stage on top of being half crazy. lol Once they settle I'll try to get a few pictures.
