Strange eggs

[MrsWagley]

I have seen a couple of these eggs now and it seems to be getting worse. First it was just a little strange texture to the shell now entire shell is lumpy with what seems like cracks that have healed. Here are a few pics. Is something wrong with my hen? I have five others and only one is laying these strange eggs.

Thank you. I am still not sure what I should do for my hen. It almost seems to be a combination of some of the pictures in the link. Do you have any advice? Maybe I should separate her from the flock, they do mostly try to lay around the same time of day...
