I recently got a stock dog pup, and was wondering if Blue Swedish ducks make good "learner" ducks to start working a herding dog on? I know Indian Runner ducks are what is typically used, but they are kinda hard to find here... I'd like to runner duck eggs to set under a hen that is going broody, but can't find any... however, someone local has 3 BS for sale.... Also- if you have 2 males and 1 female, will it cause problems with the males? Thanks!
