I have a singular Cayuga female duck left of my duck flock. Last week the male runner duck passed away, prior to that we had a couple other female runner ducks too. I was hoping to phase out the ducks, but she is 3, so relatively young still. She lives with our 5 chickens and seems to get a long well with them. Do I need to get her another duck friend? She is quite loud, but was before the loss of our male duck, so I can't tell if she is calling for him, or just doing her normal noise.
