Please help with 3m old female ghi Mojave feeding issues.

No they are Frozen thawed I wouldn't feed live unless absolutely necessary.

I had to ask, so as to rule out that the rodent was chewing on the snake, even while losing the battle- it's been known to happen, & could have caused what you described.

I'm no expert on BP genetics, but I suppose any snake can have some idiosyncrasies*, or some neurological impairment that might cause this. Not just those specific kinds that are known for it.

*I have also known a snake (not a BP) that had truly hyperactive responses to their prey every time they ate.
