Glad the patient is doing well. The smashed egg in the nest may or may not be hers, but don't assume it is. Spend a little time among the flock to get a feel for how all are behaving. These egg quality issues can be a harbinger of the new laying season, laying systems getting geared back up, and calcium levels may not be up to normal in all hens.
Just yesterday in my flock, one of my little Buttercups was isolating behind the stand that the water tank sits on. It caught my eye because normally, she's like a battery operated toy, always darting here and there. So I stood and watched her. She was very subtly hunched and then she puffed up her feathers just very slightly. But it was enough to tell me that she was possibly having an egg laying problem.
I popped a calcium tablet into her beak and turned her loose. It was about an hour before roosting time. Later, at final coop check, I saw she was on her perch with a soft shell egg on the floor under her being dismantled by the two other hens who live in that coop. She is one of my youngest, so I attribute it to being early in the season and her system isn't as supplied with calcium as it should be. So she'll get a table a day for the next several days.
