You can have khaki colored runners (Holderread) and calls (Ashton). So this might be another new duck that has the khaki pattern but other attributes from ducks besides khaki campbells. Although when the body type is so close to the campbell and the color is exactly the same it's hard for me to imagine why they would catch on as a new breed. Unless there is some other trait that remarkably sets them aside from the campbell?
The idea of starting new breeds is exciting, as long as people were careful to not let them interbreed with other breeds under the wrong impression. For instance in this case, you wouldn't be happy to get some offspring of these hoping you would get lots of eggs and then find out they didn't lay like campbells.
City Chicker you were saying the drake looks like the dark dusky pattern, I would love it if you could tell how you identified this from the photo. I have a hard time telling dark from khaki especially in drakes. I just want to learn this because I had struggled with trying to figure this out before when I was looking for dark campbells. I mean sometimes it's just a matter of how the light hits, but is there something else?
