It may just be hungry. So try and feed and see what it does.If she is being rough on it and the food doesn't seem to make a difference i would try and remove them for a couple days and see if that makes a difference in the nems size. Mine there was a huge difference after i removed her and then again when i put it back in. She just LOVES it to much for my likeing
Let me know how the feeding goes.
