Hey, I agree with what the others have said. We all try to prevent things by being proactive and the advice given here is some of the best around. But remember these snakes a pretty hardy little animals. The wind blowing the wrong direction is not going to kill your new baby. You can over think things to death and make your life much more stressful than need be.
You already realized the mistake and corrected things. My BP has not eaten in 5 months, has not lost weight but she is driving me crazy. Its just how they are.
These little animals come up against some very harsh conditions in the wild and you can find some imports that are in great health.
I can tell you are going to be a good owner because you cared enough to be worried. Relax and enjoy.
