Thanks a lot for this information! I can't wait to see what pops out of the eggs I'm going to incubate if this little guy ever gets going on egg fertilization! He's a bit on the slow side unless he's just shy around me!Actually breeding him to those can tell you in a different way - if any of the ducklings are chocolate at all, then he has to be carrying chocolate. A chocolate female can't produce chocolate ducklings unless she is bred to a chocolate male or a chocolate-carrying male.
If he's not carrying chocolate, all you would get are blue pied ducklings. If he is carrying chocolate, you would also get some lilac pied ducklings.
