I am trying to build a couple of flocks. One of Blue Swedish and one of Rouens. Actually I guess one might say three flocks because we have some pekin hoping to get enough eggs to sell. My stupid question of the day is....I have seen ads for "flying Mallards". Is there really a difference between Mallards and Flying Mallards? The reason I ask is I have become aware of someone giving away their flock of Mallards. They say they are the "bigger ones that don't fly". So I am questioning if these are mallards at all but possibly Rouens? Could this be true or do I have more to learn about the breeds than I thought I did??? Thanks Cathy "New Duck Mommy"
