There are three excepted methods of distraction.
1. Earthquake method.
2. The drop method.
3. The Roll method
Each woks very well when used properly. {PROPERLY}
The earthquake and drop method are all most the same. You drop your arm suddenly or move it up and down like an earthquake and just enough to take them off balance. Just don`t over do it, You just want to distract and not shake your bird to the point of breaking the trust. The same with the roll, you roll your arm back and forth enough to take them off balance. Again don`t over do it
When they stop biting, talk to them and tell them what a good bird they are.
I like the two bite method. Say no bite once, if they don`t stop than say no bite again and at the same time use one of the methods and when they let go tell them good bird for not biting.
Again don`t over do it. Don`t shake them to hard or over roll your arm to fast or hard.
