One hen's eggshells have gone soft

[dreamdoc]

I have one 3 year old hen who has previously laid normal eggs. She is now laying soft shell eggs that break in the nest. I feed the flock egg shells and will try oyster shells. Any ideas why this is occurring?

How long has this gone on? How many shell-less eggs? Was she laying regular eggs this year after the molt and it just switched or has it been going on since her molt?

Is it every egg she lays or just an occasional one?

You say soft-shelled. I assume this means a very thin shell but something there with a bit of stiffness in it. Not just a soft flexible membrane?

I assume you have other hens laying "normal" eggs?

Could be a few different things going on. Offering oyster shells is a good idea but I don't know if it will solve the problem.
