Hi everybody, first time posting on this forum or any forum for that matter. I'm still new to the whole bird keeping world, so forgive me if I don't get some terms or concepts right. A bit of backstory: We got a 2 month old cockatiel a few days ago (his name is Mochi) and now he seems to be hurt and we don't know what to do. Please keep in mind this is our first bird we have ever kept. This morning, he was sitting with us having breakfast when all of a sudden he flapped his wings (they're clipped btw) and started gliding to the floor. While he was doing it, our french bulldog decided that he would go after him and snapped at him but he only managed to grab a tail feather or two. It caused Mochi to lose his balance as he was falling to the floor, and he started tumbling and fell way more violently than the typical soft landings he's made over the past few days. I wasn't able to see exactly what he looked like when he fell, or what part of his body he fell on, since he was picked up before I got to the other side of the table, but now he is favoring one leg way more heavily than the other, one side of his head has a small cut that has covered his eye with congealed blood, and he is no longer standing up straight on his feet and is now rather sitting on his feet and legs instead of his usual standing. He's tried eating some food, but honestly not much. We don't really know what to do. Somebody else in my family said that he is just in shock, but when I looked it up, what he is acting like doesn't look like shock at all to me. We can't seem to find anything broken on his legs or the surrounding area, but it could just be that we are too inexperienced to tell. Does anybody have any suggestions on what to do? Does he require a vet? Is this just something that they do when they are scared or stunned? We are heartbroken that our little Mochi has only been with us for a few days and we've already let him get hurt. Please help if you can!!!!
