I'm linking videos of my duck Mable who started shaking her head now and then, a couple months ago. Her quack has changed and that can be heard in the first video. She now has this a more croaky quack that she does when she's eating. She hasn't been herself lately, stands around more staring into space more, when she used to be my most energetic and curious duck, always quacking to get out of the run. But she also just went through a molt and I didn't know if that was why she was off. She still eats and drinks and runs out to forage, but sometimes she seems disinterested in treats - it's just random. She's on day 4 of Safeguard to make sure it's not gape worms, and I have a message in to the vet to ask what diagnostics they would do for possible aspergillosis. The other option is something she inhaled. Does anyone have any strong thoughts after seeing the videos? Thanks in advance.
