Everyone who has replied has told you this is not a good idea, here and in your other topics... I'm just very confused as to why you would leave them outside after everyone in your first topic told you not to (even your mom said not to). Baby ducks are born in spring when it's warmer and they've got mother's to keep them warm... yours were born at the very end of fall, in a normally cold climate with no mother... If your ducks due not make it, don't be surprised... I just don't know why you would ask for advice from those of us who've done this many times, only to disregard our warnings... If they are still fighting, the added stress from being outside could kill them even quicker than the cold. What few precious feathers louis had are being plucked out by donald... This is like throwing a four year old outside with no coat and saying, "Good luck!"
We all know how stinky baby ducks are, that's all part of it. I have 2, soon to be four (2 new ducklings coming in a week or so) that live inside of my house all of the time... You should see how disgusting their pen gets... how we often wretch when dumping water/food pans and steam cleaning and scrubbing poop off of the pen.... but we do it, because we have to. my bf Joe does a good portion of the work, and they aren't even his ducks. they were 7-8 months old when we met but he's taken on the role anyways... Ducks are messy smelly animals, no matter what you do to prevent messes and smells....
