Hi everyone, so long story short I'm here in hopes of finding some imput as to what caused the sickness and later death of my tiel. I had 3 tiels, one male and two females. Last Tuesday my male was his normal self, I typically let them out of the cage when I get home from work, and they all stay in the living room with the occasional fly down the hallway and back. That evening he fell behind the wall mounted TV, his wings were both outstretched vertically in a V, so he was stuck. He was like that for a moment or two before i noticed a tapping sound he was making behind there. I quickly got him out and he appeared uninjured, aside from alot of panting(breathing), but he calmed down shortly after, and seemed himself the rest of the evening, he tried to fly and didn't get much lift and I assumed because that wasn't a comfortable position to be stuck in and was probably a little sore haha. The next morning I woke up late for work and didn't pay a whole lot of attention to how they all looked in the cage, but I know they all were on the perches and looked normal to me. So here's where it goes downhill. I got home from work at around 7pm Wednesday and noticed he was by himself on the bottom of the cage, all puffed up and wings slightly drooped. All the typical sick tiel symptoms from what I've read, his droppings were a big indicator being as they were practically water. He would drink water if I brought it to him, but he seemed very weak and his movements were slow and labored. I kept him close to me for a while so he would stay warm, but his condition seemed to worsen every hour. He started to become twitchy, like muscle spasms, intermittently all over his body, including his beak facial muscles. Eventually it seemed he could hardly stand on his own, and when he would move he would fall on his face and stay like that, I made him a comfortable cloth bed and let him rest, at this point he could hardly move on his own at all. I made sure he was stable before I went to bed myself, but unfortunately as i suspected he didn't make it through the night . His eyes were still open but he wasn't there anymore. It was very hard to loose him like that, I would of taken him straight to a vet but there were none near me that were still open that time of night, let alone one with an avian specialist. I just want to know if anyone has seen something like this before, and that being said any additional preventive actions I can take to make sure the same fate doesn't happen to my other two.
