What is a mule duck?
Muscovy and domestic ducks (such as the Pekin – which were developed from Mallards) are very different as they have been genetically isolated for over 50 million years. They can be crossed but you get some very interesting results. If you cross a Muscovy male with a Pekin female you will hatch moulards (or mule ducks); if you cross a Pekin male with a Muscovy female the progeny are called hinnies. In Europe and in Asia many mule ducks are produced because of their large size, quality liver and reduced fat content in the carcass. Artificial insemination has been developed in ducks due to the desire to produce mule ducks. If left to mate naturally, the fertility is only 20-30%. Artificial insemination brings the fertility up to 80%. Whereas a Pekin takes 28 days to hatch and a Muscovy takes 35 days, a mule or hinny takes 32 days to hatch. Approximately 60% of mule ducks are males. Some of their characteristics are like the Muscovy as they are large, quiet, slow moving and have long claws
