Hi all, I have a bunch of duck eggs in my incubator right now. Most will be mixed breed with khaki, pekin, and Rouen. I've looked up how what most of the crosses that we will come up with will look like as hatchlings. But my question is, is it possible to tell any mule ducklings from the others at hatch? Are there any specific signs to look for? Here is what I've gathered during my searches: Rouen x Khaki - Looks very similar to a rouen Rouen x Pekin - Looks like Rouen duckling with more yellow fuzz/broken solid patches Khaki x Pekin - Black with white bibs I have 2 Muscovy drakes (1 black and 1 chocolate). I have seen them mate with the other ducks so I have no idea what's in the incubator. I have somebody wanting to buy most of the ducklings that hatch, but want to keep any mules and the 'scovies for myself.
