great post I have a love hate relationship with ducks and Chickens, I keep and breed both as well as Turkeys ,quail and everything else here that lays an egg.
In the long turm Ducks are the winner as the last poster said if you have the room to let them free range. They do have there down side they do not lay an egg for the first six months, but then they catch chickens up and pass them by a mile.
Chickens are chickens they scratch, wake you up, fight, come in side your house jump on your table eat your salmon sandwitch. I hate them this week
