Sometimes, the cage can be humid enough, but its just not enough for the snake. I had a rat snake stay opaque for about 2 weeks once. His cage was plenty humid, but he still didn't drop his skin. I though he was going to blow his shed at first. His water dish wasn't very big, so I put one in there that he could completely submerge and soak in (which was hard because he was a GIANT at almost 8 feet long) and after about a day of soaking, his eyes went clear and he shed the next day. If she does blow her shed, don't worry too much about her. Sometimes, a feeding can help stretch the skin a little bit, enough for it to loosen up. Other than that, I wouldn't worry about it too much. Some shed's take longer than others. Sometimes it depends on how much the snake has grown since the last shed to determine how big theis shed will be. Keep me posted and let me know ehat happens.
