I'm really not sure what happened, two days ago when I returned home I noticed one of my Cayuga ducks isn't quacking and she is making a weird noise, and acting different than she normally does. She will walk slower than her sister, wont climb into the pool right away, doesn't splash around in the pool. Just the other day both of them were chatting it up, now she can't even.
