Gidday everyone, My 2 mallards are 6mths old and want to sleep outside under the trees with my bunnies, they are all freerange. Do they tolerate the cold nights with frost? I keep thinking that I'm going to wake up and go outside and find 2 frozen ducks! They must know what they are doing and I like to keep things natural as far as habitat. But gosh Ive made them a comfy hay carpet in an open boxed home and you would think they would want to sleep undercover., sometimes they sleep in their pond! I guess the ducks in the wild sleep undercover, When I go out the back at night the ducks come up and say Hi, "what.you.up.to?"then go back under the trees.We dont have any predators here otherwise I would force them into their house. Where do your ducks sleep? Where do your ducks sleep.
