Also most of the hatcheries offer eggs for sale. You can also check out eggbid.com. They have some fun things sometimes. Have fun and keep turning.

Just a cautionary word, before you order any Mallard duck eggs check with your state agency in charge of enforcing the laws concerning wildlife. Mallards are a migiratory waterfowl and fall under the protection of the US Fish and Wildlife Service. In some states you are required to have permits to raise or keep certain species of animals, fowl, fish or reptiles. In Missouri you are required to have them for Mallards, Canadian Geese, Ringneck Pheasants, Bobwhite Quail, Eastern Wild Turkeys, Whitetail Deer, Raccoons, Opposums, Cougars, Bears, and other animals. Do not make the mistake of ordering hatching eggs for a native species without checking first, if you do, someone in a green pick up truck might stop by one afternoon, load up your fowl and hand you a citation to appear in a Federal District Courthouse.
