Kinra, I don't think you have anything to worry about. I feed my snakes in their enclosures, both live and f/t and have never had a problem with cage aggression. Of course, it can happen, but if your baby is good-natured now, as long as you continue with regular and gentle handling, there is no reason she'll change. You could try hook training if you feel more comfortable with that. Boas are large snakes and the females in particular are impressive and it is easier to start that training now while she's small. But I doubt you'll ever really need it. I'm willing to bet that the reason she struck at you with the "zombie dance" was simply that she missed her prey and almost hit you instead - not because she was upset. And I can't blame any snake for striking right out of the shipping box, lol...
