They are soft shelled or shell-less eggs.  While she is a new layer, you stated she was laying normal eggs for a couple of weeks.  Do they have access to enough calcium?  You can add oyster shell to the coop, use a high calcium layer feed, and crush and feed egg shells back to them.  I would also buy BOSS (black oil sunflower seeds - in the shell) and feed them.  They are very healthy for them.
Do the birds get to free range? They will find what they need nutritionally if they can free range at least for a bit each day.
