I have a small hobby farm. I have chickens and I have interest in trying ducks, but I don't have a pond and I live in a cold climate with long winters. Is it possible to keep ducks healthy and happy inside a barn during cold winter months? How could I provide them with the water they need inside a barn without it being too labor intensive and make too much mess in the barn? In the summer, how large a water source do they need if outside? An old tub? A small plastic basin? Maybe I should just stick with chickens? Any ideas would be appreciated!
