You are right though about maintaining them in the winter. I have lots of heated water bowls and access to electric for them. If not it would be a real pain carrying water to them all of the time because of the ice in the bowls without being heated.I hope you don't mind me joining in. I have 20 ducks and they can do better in the cold than in the heat. Mine have been just fine at 14 below F here in Ohio. I have lots of shade for them in the summer because the heat is hard on them. Good luck with your ducklings. I have 6 right now, 3 Mallard, a possible Hinnie since the drake was a Black Swedish Call Duck and the Hen was a possible Muscovy and 2 Fawn and White Runner Ducklings that I am hoping at least one is a female. I also have a Mule Duck. The Drake was a big Muscovy and the Hen was a Rouen Duck. She can't lay but my Hinnie will be able to if it is a girl. The eggs will not be fertile though which is fine with me.
