As @ kaizen said...she is full of eggs and if she has t got a proper place to lay them she will likely become eggbound. Because her arm is broken, even if she has a proper place she won't likely be able to dig a hole.
You need to have an egglaying bin in her cage right away. I recommend that you use washed play sand that is just barely moist enough to hold a tunnel...and because she has a broken arm, I recommend that you dig a tunnel for her.
If the calcium you have been giving her has D3 in it, because you were using it too often she might have the MBD due to a D3 overdose.
