VetRX is basically vicks vaporub, it won't treat anything.
If droppings are normal, then it's more likely that this is a laying issue.
If it's a soft shelled or shell-less egg, those can be very hard to pass and can make them feel very badly. Once passed, they usually perk up. No way to know for sure if that's the issue, you might not be able to feel that.
I would give her the calcium, keep an eye on her. If it's cold where you are, then I would bring her into a warmer place until whatever is going on is figured out. Feel her crop to see if it's empty, full, hard, soft & squishy, etc, and then feel it again first thing in the morning before she's had food or water, see what it feels like then. It should be empty then. Let us know what you find. I would do as previously suggested, go over her thoroughly head to toe, part feathers, look for any lice/mites, look for any hidden injuries, check feet and legs. Make sure nothing has been missed.
You can also give a B complex or super B complex tablet or capsule daily, that may be helpful and can help with appetite. Human ones from any pharmacy are fine.
