Warty eggs anyone?

[MenagerieMan]

For a couple of months now one of my Americanas (Easter Eggers), has been laying eggs that look warty. Her egg shells are also thinner then the rest of the girls. Not sure why or what is causing this to happen. I have made sure they have enough oyster shell thinking it might be a calcium thing... But nothing has really changed. Sometimes the bumps a large and sometime small. But they are usually always there.... Any thoughts or advice??

They are calcium deposits, harnmless to the egg contents. This article talks about common egg problems and their causes:
