First off, "reputable stores" don't sell snakes that are full of mites...
Second, it's very hard to read your "wall of text"...please break things into spaced paragraphs in the future, assuming you want ppl to read & answer you.
Third: your snake is merely hungry! BPs are ambush-predators and when they wait in the hide, just peeking out, that is how they "hunt". They are not active hunters,
they just wait for clueless prey to pass by. Your warm & wiggling hand appears to be prey to her, so you may want to use "tap training" so you don't get tagged.
Feeding f/t: good job getting your hungry little one onto f/t.Make SURE that mites don't come back...they often do. (how did you eradicate them?)
Hunger: what size prey are you feeding? it might be too small & that's why she's so often hungry, but all in all, that's a "good problem" to have. Welcome!
Posting: you posted the same thing twice (please don't do that) now a mod will have to remove the other one...it gets confusing if ppl happen to answer on
both threads, not realizing there's another.
