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.
another has a free floating yolk so I’m guessing no good and other smaller egg looks clear but I’ll keep my hopes up on that one since it’s only day 2. Probably should have picked up more than 6 eggs but didn’t look into incubating and hatching until I got them (silly) and realized they are apparently much harder to hatch than chickens.
