I have two hatchling ball pythons that have a bit of an attitude problem. I have always had very placid ball pythons, and was a bit surprised when the first one struck at me. I am handling them every second or third day, trying to get them used to being handled, and I do not back down when they act aggressive (not rewarding bad behavior). This is just new to me, and I am not sure if there is anything else I should, or should not be doing. They are both well fed, and I do not believe the striking is a food response. I know it will take time, just wondering if anyone has any tricks or suggestions.

I do not think this matters, but just in case, the two biters are the only two that I ordered and had shipped to me. It makes me wonder if the shipping process has something to do with it.
