I have a nice flock of these great ducks with more pipping as we speak. They are friendly, quiet, wonderful mothers and great egg layers. They do reach full size by about 3 months but won't actively breed or lay until around 6 months. The only thing I dislike is that they are escape artists. I allow mine to free range on my property yet they still find every nook or cranny in my fence to escape, hence I have lost a few to predators, whereas my chickens are content to stick around my property and I've only lost one or two to predators. If you are interested in getting them I totally recommend it!
