I have had four hens since end of June, all four have been laying well since end of July (20weeks old ).  The have quite a large run (25foot X 20foot, deep bark floor), I feed them layer pellets, veg etc and corn in evening  I also scatter grit around the run and they have a bowl of grit in the run. In the last couple of days I have had two eggs with papery/soft shells, completley normal formed egg inside just soft shell on outside.  I assume it is the same hen that has laid these two but the other three have laid normal eggs.  Any ideas whats wrong or what I'm doing wrong.

Do you give them oyster shell or feed them their own egg shells (washed, baked then crushed)? The grit is to help them grind their feed up but they could do with the oyster shell etc as a form of calcium to make stronger shells.
