No, no, no!! Don't be discouraged. If you could read the posts that I made about me and Dooby, you would be surprised to see that it is almost identical to your situation. I was afraid of him biting me and I used to pull away my hand, but.....after putting a video clip up on here and people seeing what was happening, the advice that I was given was brilliant. How I managed it was.....I got this thought in my head..."Well, he's bitten me loads of times and I know that hurts, but it can't hurt more!" So, I just went for it...I made him step up and he bit me, I just kept going at him until he had to step up. You have to show that you are confident and that they really don't bother you. I swear to you, within a couple of hours, Dooby had given up biting. I don't mean go at them again and again and again, just put your hand in her cage confidently and don't pull back if she starts to lunge or bite you. I know it's difficult, I had six months of **** with Dooby, but really, it is the only way. You can sit quietly and talk to her for a couple of days, then gradually, gradually build up her trust again, open the cage, move slowly, talking to her all the time and when she goes to bite you, just move your hand forward a little quicker so that she can't have a good chomp on you, if you slightly unbalance them when they are on the perch, they forget about biting and step up, grit your teeth and bear it. I promise you, give her a day or two to get used to the fact that you aren't going to give in and that you are not afraid of her and she will be better. The point is, if you are a little hesitant, they pick it up, the can sense that you are not really in charge and they take over. It's like a child with a tantrum, if you keep letting them get away with it, the will stamp their feet and scream every time they want something. In this instance, your little lady wants you to leave her alone, well, you are doing that by withdrawing your hand, she knows that if she bites or even goes to bite, you will withdraw your hand, thereby giving her what she wants. Believe me, I KNOW it's hard, I too am an older one with thin skin (literally) on my hands and yes, Dooby hurt a couple of times, but if you can just grit your teeth, move towards them slowly but confidently, I'm sure it will all work out good in the end.
