I'm still trying to work with one of ours that's bitey. (We named her Jezebel)
She's about 1700 grams, and feisty! I can sometimes pick her up for a minute or so, but I'm always on the defense with her. If not, she'll tag me. I can't figure out why she's this way. She's in the same conditions as the others. 55-65% humidity, 91 hot side, 81 cool side. She won't use a hide. She's an okay eater, not the best (won't take F/T yet).
I'm hoping that over time, she'll calm down and let me hold her longer, and that she won't just keep being mean.
The people I bought her from said she bit the male they tried to pair her with...we'll see how it goes.
Good luck, and keep us updated on what happens.
