soft shell eggs

[cjc]

My Black australorp keeps laying soft shell eggs. She gets layer feed,oyster shell and walks around the yard. She will lay a few good eggs and then she gets goofy again.THe other 3 girls(EE,SW,RS) do a great job!!They are all around 10 months old. Could my "Betty" be sick?

I'm having a similar problem, and I posted it here, but haven't gotten an answer yet:

My hen is one year old, at the beginning of May. If your hen has just started laying, soft-shelled eggs aren't so odd. My hen was laying good eggs for 5 months. Then she started laying wart-covered eggs and after a few weeks, soft-shelled eggs. Maybe someone else knows what's up.
