So I've had several of these wrinkled eggs. Sometimes they have a thin spot. Oyster shell is offered at all times. Thinking this was a calcium issue. Now I got this egg... It has the banded looking wrinkles and an extra lump of shell on top! Am I being overly paranoid? I have a girl with eyp about to go and another with what I think is a lash egg stuck! When it rains it pours problems around here. All girls are about 3. EYP hen is an RIR and the other two are BL. Everyone except RIR with eyp is acting, eating, pooping normal. Is this just a rash of age related problems?
