I have a one year old lovebird who flew into the side of our bathtub about five days ago. He seemed stunned for about 5-10 mins after it happened. He sat on my shoulder for a bit and then I placed him back into his cage. There were no obvious injuries. However for the last five days, he has not been as active, does not show much interest in coming out of his cage but he is still eating and drinking. He has come out of his cage a few times but usually sits on his cage a few minutes then goes back inside. I am extremely worried about him. Could he be dying?
