Still not eating

[Bogertophis]

Yup and this is only the 2nd year she's done this, ...

I've kept multiple BPs years back & they mostly do this when they're a couple years old (once they mature). If you want a snake that eats regularly & reliably, get a rat
snake (including corn snakes), bull/gopher/pine snakes, king snakes, even an Australian spotted python will happily eat all year. It's just not in a BP's job description.
