my ball pyton has feeding reguarly and no signs of any illness but the past 3 days (she ate about 5 days ago) she has been coiled up ready to strike laying on top of her wodden hiding log. I generally leave my snakes alone for the next two days to let them digest. Anyway today i noticed on her back starting from her head to about half way down her body a white glaze. Does this aggression and white glaze mean she is getting ready to shed?
