what do you mean by anti social? Is she trying to bite or just hiding a lot?
Is she eating, pooping, drinking, and acting normal otherwise?
Has anything else (besides shedding) happened in the past week? ie- Has the temp dropped or raised drastically, has the humidity changed drastically, did you change something or do something different in her cage, has your routine with her changed in some way?
Corn snakes need a while to acclimate to a new environment, and babies tend to be flighty and snippy at times anyway. Developing a "Routine" and regular handling, and familiar surroundings, with steady correct temps lead to a healthy happy snake. If something changes, then the snake may have to adjust to it.
