I have a Barred Rock and a RIR both laying eggs. For the last week or so, every time I go to check the boxes I find an egg from one of them (not sure which) that has a small hole in the pointed end of the egg with some strange lines around it. It is never broken through the membrane, and the broken piece of the shell is always there, so she is not eating it. I will post photos of the egg with this post. Has anyone seen this before, that can shed any light on the situation?
