Mental groove open?

[JAGpenguin]

After really thinking about what's different with her compared to the other BPs, I think I might have figured it out. The BP in question is BP2, the one who used to be overweight, but now in perfect shape, triangular and no sudden taper from the cloaca to the tail thanks to the advice from you guys .

But now that she has grown, she is now my biggest snake. I however, for the last few weeks, had been feeding her rats at 30 grams even though she was around 350 grams after pooping (approaching 400 grams with food inside) to maintain that body proportion. One thing I noticed though was that, after just 1 day since feeding day, this BP would roam endlessly at night (not during the day) and she kept trying to reach the top of the terra and rubbing her chin against the screen top for hours at night, while the other snakes would just chill in their hide sometimes for 2-3 days after feeding. It couldnt be husbandry because every BP has the same model of terra, substrate, hides, and in the same snake room, therefore same temp and humidity. Yet she was the only one behaving like this. To stop this endless roaming at night, I tried giving her a bigger meal last week and the endless roaming at night had stopped.

So I am thinking, maybe that stuck shed on her chin was not stuck shed at all but rather the outer layer of her scale getting rubbed off from her rubbing her chin against the screen top, and this would explain the ellipse mental groove too, maybe the scales surrounding the mental groove were pushed aside from the constant rubbing of her chin against the screen top. Her last shed was 2-3 weeks ago and it was one solid piece. So it was weird to find stuck shed weeks after a perfect shed. This is my best guess. I also checked the inside of her mouth to see if anything was wrong, but nothing.

Right now she is at about 400 grams with a couple rats in her, and I am going to try to give her 40-50 gram rats weekly, instead of 30 grams that I used to give. Give it a few weeks, and check back on her mental groove (considering that she, from now on, will stop rubbing her chin against the screen top because of hunger). I think this time it really is time to upsize the meal
