That behavior suggests an egg issue. When I have a hen doing that, especially late in the day, I give her a calcium tablet and leave her in the nest overnight.
This is typical behavior when an egg, usually a shell-less one, is hanging up. These late day eggs often end up falling out of the hen during the night from the roosting perch, and then it's too late to know which hen is in need of calcium treatment.
So take advantage of this situation and treat this hen proactively.
