My cockatiel
My cockatiel died very suddenly.She was at the bottom of her cage she started to spread both of her wings.She normally does this when she her space so we gave her space and left her alone.A few moments later after we left her alone she started making sounds that sounded like yelps and then we found her lying down on her back and not moving.She passed away and we want to know if there was so reasons as to why.She was 5 years old.
