Hi I am hopefully going to be getting three ducklings here soon. We'll have them in a run in the backyard so they don't get into the horse trough. How much room will they need in the run? I have heard ten square feet per duck, and 4 square feet in the coop. The winters here get pretty cold, so would they need more space in the coop? I think I am going to get an Indian Runner, Blue Swedish, and a Cayuga. What height of fence will the need? We don't have any neighbor dogs or raccoons or foxes or anything that we know of. The only think we have is a hawk, but we have lived here since June, and it hasn't bothered the chickens, and they free range. The run would be on a hill, is that okay for the to be on all the time? We'll have sure they have a good size pool, because it gets pretty hot in the summer sometime 100 for a while What type of fencing is the best and cheapest? I saw someone use that green roll out stuff, would that work? Thanks! I know I'll have more questions about this!
