If you want the Runners that look like bowling pins on legs, you must buy from a serious show and hobby breeder (or Holderread, who counts as a show breeder). The hatchery Runners simply look like mutts with a bit of Runner blood in them.
Your ducks are very pretty and they will make very nice pets. If you want real runners, or if you intend to breed them, then buy some SOP runners. Tons of people breed them and they are readily available. Just ask where the breeder's stock came from because there are people out there who buy hatchery stock and breed it and call themselves "breeders". All those guys are selling is hatchery quality.
