Egg incubation is done under favorable environmental conditions, possibly by brooding and hatching the egg.
The White Muscovy and the Pekin are the two most common purebred, commercially farmed ducks. Hybrids of the two are hardier and calmer, in addition to exhibiting natural hybrid vigor.

The Muscovy is commonly reared for meat. [4]: 78 Mulards from the crossing of a Muscovy duck (Cairina moschata) and a wild-type mallard (Anas platyrhynchos)In commercial production, it is often crossed with a mallard-derived domestic duck such as the Rouen or Pekin to produce the hybrid known as a mulard.
It is widely agreed that the mallard (Anas platyrhynchos) is the ancestor of all breeds of domestic duck (with the exception of the Muscovy duck (Cairina moschata), which is not closely related to other ducks). [35] Ducks are farmed mainly for their meat, eggs, and down. [36]
