OK, I am going to put my 2 cents in here and will say I have never "tamed" a burm but....

I know my albino balls do not see well and while they are not super defensive they can be quite fun on feeding night if the rat is not hotter than me.

So if an animal does not see well, what senses are left to a python? Heat, smell and touch. You can try putting a well worn stinky t-shirt of yours in the enclosure with the animal to get it used to your sent. Always touch the animal with something that smells like you before grabbing it. As long as nothing extremely negative happens during this process the animal "should" begin to associate your smell and the procedure with nothing bad happening to it.

Good luck, a burm with an attitude is not something I would be wanting to deal with when it grows up.
