We're tight on money thanks to some health issues, so a vet visit isn't in the cards until this Thursday. But Wobbles has begun to make rather alarming high-pitched sounds. He'll sporadically hunch, throw his head sharply downward and go "SQUEEK" like he's trying to dislodge something or it's the world's biggest hiccup. He also occasionally jumps up and starts quacking loudly, as if he's started or in pain. This happens even if there's absolutely nothing going on around him. I don't think it's an impacted crop. I've palpitated his crop and chest area and can't seem to find anything out of sorts. I'm having less luck locating his gizzard, having such a teeny body it's a bit tough to feel for organs externally. My fears are that he's either got a bruised air sac (probably from when he crash-landed into the fireplace last week), something's caught in his gizzard or he ate something bad. Being an indoor duck I'm paranoid about hardware disease, even though my husband and I are both careful about cleaning up any and all metal, you never know where a loose coin or paper clip could turn up. But even THAT seems iffy since he was just x-rayed last month and it takes a while for metal objects to dissolve to the point of blood poisoning. He's still eating, although not as much as he used to. However, it IS wintertime and it could just be run-of-the-mill seasonal appetite change. He's also just as active as always, the only signs of discomfort is when he does his painful-looking quacks and strange hiccups. I keep trying to capture it on video but it only happens a few times a day, so it's been difficult. If anyone is familiar with these symptoms, please let me know ASAP. I don't think he's in immediate danger, but his pain level concerns me as I know ducks are masters at hiding when they don't feel well.
