EE had a soft shelled egg and then no more eggs ... what could it be?

She's about 2.5 years old, seems to be in good health still. Running around eating and drinking fine with the other 4 chickens. I'm worried because she hasn't layed in a few days and usually she lays almost every day.

I have no idea, but am bumping you because my RIR is foing the same thing. She layed very thin shelled eggs, then a soft shell, and no more for the past month.
