need some advice on a soft egg layer.

[BARobbins]

My 13mos old Wyandotte for the last couple weeks has been having a soft egg just a thin membrane and this AM makes 2 in a row. we have their layer crumble and oyster and egg shells available. No one else has this issue(flock of five) any advice on how to get her more calcium, I assume?

Can get some Equate brand calcium citrate with D3 from WalMart, or another generic from a pharmacy? Give a 300 mg tablet daily in her beak to swallow for a week, and see if her shells get harder.
