Hey man,
Hold off until you get the new cage. If that doesn't change things, I fully support your thought to sell or place her. Maybe a trade for another?
Not that you need a go ahead from me, but I know somewhat know how you feel. I've been a bit irritated with Wallace since he hit his adult size. Lately his little, male brain makes him a bit loopy. He had a go at me today even after I tapped him with the hook. The situation was still my fault as I know I have to get him moving the other direction completely before trying to remove him.
I finally got hold of him, and he did his damn tail whip and emptied half the substrate out of his cage onto the floor.
After that, he was fine, however I started to wonder if the hassle of dealing with him was worth it.
I guess the point being here is this. We all have limits, and other obligations. Most of us, I would assume have other hobbies and other aspects of life to channel our energies.
You are still getting grounded in your teaching/educating career and don't have "helpers" at the dial of a phone.
If that new cage doesn't fix things, you've covered it all and should not have to have a hobby become a life stress inducing situation.
Good luck brother!
