So I have this production red, not sure how old she is. I got her in July, she was full grown and laying. I think she may be around 2-ish. Anyway, off and on this winter she has layed shell-less eggs, just walking around the run, squats and lays a soft egg. Today I noticed her doing it again but the egg came out. The membrane was hanging out her vent. I pulled it out, didnt see any shell fragments.
