Today, I noticed 1 of my BPs roaming during the day, which has never happened before with any of my BPs. I took her and inspected her and I noticed two things: a piece of stuck shed near her chin, which I have removed by soaking in water and gently let the snake's head slither through paper towel, but it is the other thing that caught my attention. I saw her mental groove (the line along her chin) being open, it is more like a very sharp ellipse rather than a straight line. Is this normal or caused by something else? Please advise.
