I have a red star older hen who a while back started laying soft shell/thin shell/no shell eggs for a while and then went into s slight molt and quit laying for a short while. This morning she laid a no shell egg along with a hard cream colored mass about 2 inches. Looked like a petrified abortion. She seems to be fine and eating well. Does anyone have any idea of what this might be? She is about 4 or 5 years old. She used to be an excellent layer presenting a large egg just about daily.
