We have 13 chickens with a moveable 6x6 chicken tractor using the paddock system, moving our fencing every 7 days or so. We’re adding khaki ducks (and a guard goose) in the spring. Question: we have a natural pond next to where we keep our chickens. Our chickens don’t have access to it. They have to stay in fencing all the time due to predators and a road near us. Can we allow our ducks to free range on the pond during the day and close them in the fencing at night? Would they fly away if allowed to free range? If i can free range them during the day, how hard would it be to corral them for nighttime? At night would they just sleep in the fenced in area, or would I place them in the moveable chicken tractor, too?
