This is a long post, for that I am sorry, but I am requesting advise from the knowledgable African Grey owners, especially those that have dealt with abused or rescued birds...
I got my CAG, Stormy, in Feb 2006. The woman I got him from was going to use him as a breeder so he was not socialized nor handled much. He lived in her basement with all her other birds for the first year of his life. She was able to handle him, but she told me that he wont trust me until he gets to know me. I was pretty new with african greys, but familiar with several other large birds. So I accepted this and took him home with me. Stormy was not named when I got him, but on our 3 hour drive home, he growled and screamed at me. He sounded like rolling thunder and I named him Stormy.
When he first came home, Stormy would lunge at me, making every attempt to bite. After much work with him, I was slowly able to stroke his beak, then his head, then neck. I got to the point where I can rub under his wings, lay him on his back in my arms and hold him like an infant. All in all, I really made great progress with him.
Last year, I moved across country and Stormy seemed to change, he was leary of coming out of his cage. When I tried to take him out, he would scream and jump for the bars on the cage. If the door was open, he would freak out and flap all over his cage. I dont know why this huge difference in him. I had moved in July and in December a friend of mine told me that she has always wanted a bird, but she didnt want one that liked to be out of the cage, cause she didnt trust her dogs/cats. I thought it might be in Stormy's best interest to rehome him. My friend bought him a HUGE cage, so that if he was going to live inside the cage, he had plenty of room. She has had him for 6 months, he started coming out of the cage again and has increased his vocabulary. (She doesnt work, and is home all the time). Two weeks ago, she gave Stormy back to me. He now goes in and out of his cage freely.
What I need help with is that Stormy gets very untrusting at times. He was like this before he went to my friend's house. When I go to pick him up, he steps up most of the without issues. But other times, he will run to the other side of his cage and climb down the side. When he's being held he will growl. He has always made this growling noise since I got him. Some say he sounds like a perculator. At times (he hasnt done this for a few months now) he would just flip out. Screaming, flapping all over either inside his cage, on top of his cage, or even on the floor. I dont want him to have to live in fear, or have these explosions of psychosis. I dont want him to step up on my hand and be carried around because he feels like he HAS to. I want him to WANT to be out. But I feel like whatever is causing him his issues to growl, and occasionally flip out is something that must have traumatized him early on. What can I do to help him get past that?
We've obviously gone leaps and bounds from how he was when I first got him in 2006. But I almost feel like something is holding him back from trusting.
