Hi, I got my 2nd African Grey about 4 weeks ago, and today she passed away. She was about 6 months old, and up until a day or two ago seemed to be the epitome of health. She was friendly with everyone, very sweet and loving, and very outgoing. She was very active and alert, and we just are at a loss as to what could have been wrong with her. Friday evening she was a little more quiet then normal, but nothing alarming. Then on Saturday we noticed she was not wanting to eat as much as normal and her feathers were ruffled. We thought maybe she was a bit cold since the weather has suddenly changed around here and put a heater by her cage so she was plenty warm. Then yesterday she didn't touch her morning vegetables, and just sat on the bottom of her cage all ruffled up. She would still walk around if you put her on the ground and would step up and perch on you too. But, since she just wasn't acting normal we made an appointment with the vet for first thing this morning. Well, this morning we got up and she steped up on my hand to go to the vet, but just on the short drive over there suddenly she just lost all energy and laid on my lap on the way there, and then she passed away in the vets office as we were waiting for him to come in. I am just trying to figure out if anyone has any idea what this could be? Sorry for the length, but I wanted to be able to give some back story so you knew the situation. We have only had her a short time, but other then these past two days she has just seemed as healthy as can be. She had a brand new cage, got fresh vegetables every morning, and always had fresh water, a full bowl of pellets and a full bowl of a seed/nut mixture available to her. She slept in her cage at night, but would be out all day either going around the house with me or playing on her play gym. We are so sad and just can't imagine what happened. We would like to know if anyone has any idea just so we can have some closure. Thanks in advance. Suzanne
