Personally I wouldn't mix a sick feral duck with my ducks. I feel that would cause my ducks stress and possibly expose them to disease and parasites. My ducks used to be feral and they had internal parasites, external parasites, and infectious bronchitis - so I may be extra paranoid.
When one of my ducks is ill and in recovery I put about 3 layers of towels on the floor of my bathroom. I change the towels about 3 times daily and do a lot of laundry.
