Since this afternoon my 11 month old Black Sweetish has been weirdly quiet. Usually when I talk to her I can get her to quack pretty much on cue, but no matter how much I try she will barely make any noise. I tried to get her to talk by giving her some greens; she always gets excited for them. She ate excitedly for a few moments then she started just picking at her food. A few minutes later she shook her head and shook some greens out, which she promptly ate. This seemed to make her feel better, but I still can’t get her to quack. This is NOT normal for her and I am very worried.
