Have you tired carrying the little fella around on a perch stick like I suggested? That way, he will walk up and down it, thereby getting closer to you. That is how I trained my baby. She was MEAN and I even hand-raised her! Talk about biting the hand that feeds you
With the perch stick, you can spend so much more time 'near' him because he will be far enough away to be comfy. Plus, some birds just dont like the feeling of skin. If I have a 'wifebeater' on my Boo wont step up on my shoulder, otherwise she literally kills herself trying to get there as fast as she can. You have clipped his wings, right? If he flees from the stick put him back and back and back. Talk to him like a baby and remember... dont hold constant eye contact for more than a few seconds. Try glancing to his eyes then chest then eyes, like that.
Sweetheart, I promise you if you continue to be a devoted parront the day will come when you too can kiss your baby. I am beginning to think you may not be forceful enough with your baby out of fear of being too forceful. Keep this rule of thumb in mind... you are the boss. You must keep him safe. To do that, he must know what is expected and know that you will not stop until he listens. It takes a sick amount of patience. Before these girls, I had none. Now, that has changed and I have improved as an individual as a result.
Anyone that is afraid of bites, not that you are, will NEVER get anywhere with their bird. It takes a million nips to get the slightest bit of progress but once the progress is acheived it is like riding a bike, they never forget.
Baby was so mean I couldnt handle her until I literally offered myself to her to bite. All the sudden, it wasnt so much fun for her. This was reverse psychology on mine and her part. I would put my hand in her cage and tell her "bite me, I dont care, but you are coming out and we are going to have fun". She was big on lunging

He will lunge and bite you a few times but DONT move. After only a few times of that he will see YOU ARE THE BOSS and his bites get him nowhere. If you ignore him when he lunges, he is going to continue because he doesnt want to interact. He wins.
Irns mistake kindness for weakness and take full advantage of it. They are stubborn as mules and we must be too or hang it up.
