I'm currently working on the tank..moving it away from the window will be my best option..The arm issue isn't from the stuck shed. The shed may have been tenacious due to the angle, though. But that really, really looks like a break. The more recent pics look as though it is healed from when the pic of your background was taken, though.
So, forcibly removing her may (probably, in fact) have been what caused her arm to be broken in the first place. Try to enforce some boundaries with your family; have them wait until she climbs out on her own, or leave her be if she doesn't. Otherwise you run the risk of causing more serious injury, in addition to causing stress and degrading trust.
Be careful with the tank by the window. Reflections of herself as well as things outside may stress her out. Plus, as the season warms, the tank may become dangerously hot, especially if there is direct sun even for a short period. Where do you live (state)?
I'd recommend moving the tank, and if you possibly can, switching it out for something larger and with better airflow.
Again, good job asking for help. I hope you're able to help her before it's too late.
I live in Indiana,the weather here is a bit weird...it's hard for me to get her outside because I live near a highway and I don't know if that would cause even more stress to her..and I hope to..I'll feel terrible if she dies..I'm usually all about animals..I love them and I'd hate to see her die because I wasn't able to properly take care of her..
