Yesterday I was in the kitchen with my mother and a friend of the family and I was answering the usual boring questions when I heard almost human like screaming. I ran up the stairs but Kiwi was their fine as usual. However when I looked into the cockatiel cage feathers were flying and my rat was on top of my bird. I reacted quickly and grabbed him off her back. He started to squeal and scream and hiss. I plopped him onto the floor and he ran behind his cage. (Which is on the floor) I looked into the cage and Stella was on the floor hissing and huffing. I gently lifted her off the ground and held her to my chest. My mother ran up the stairs and we checked her out. She appeared fine. I took her downstairs with me to keep her close and watch her. She was missing quite a few feathers from her back but appeared fine. I went upstairs and returned her to her cage. I found Nico and put him back in his cage as well. Turns out the latch wasn't fully closed and he pushed the door open. I went back up their and she was on the floor of her cage. We went to the vets but they said she appeared fine and they didn't want to stress her out further with X-rays. I haven't seen her eat anything and I think her wing may be broken but I don't know. I had her on my knee and she jumped off. She landed weird and started dragging her wing. I feel terrible. I wish the vet would have done more. This is exactly why I was going to give the cockatiels away. I actually may have found a home, their are a few people interested but I won't give her away until she is totally back to health.
