It would be good if you offered chicken grit, which is sized to be correct for them. It's crushed granite. The driveway gravel may be ok, but I can't say for sure.

I see no reason for her not to be with her flock mate, as long as she's not attacked or kept from food and water. She may very well be happier there. If this is a reproductive issue, then it will likely be an ongoing thing. Digestion can slow, sometimes stop completely as the condition advances. Time will tell.
