A few years ago, we got a pair of ducks. One suddenly passed today, and we're not sure why/how. Our remaining duck is very much grieving, and it's absolutely heartbreaking. I would like to get her another duck friend to assist with her loneliness, but because we don't know how our duck died, we're hesitant to get one right away in case it was something that's contagious. What do you all think would be a proper "incubation" period for anything that may be contagious before we add other ducks to the mix? I'm trying to find a balance of being responsible for other ducks and not subject them to illness and while also understanding ducks are flock animals and need friends. Any thoughts and advice is appreciated!
