I have searched and searched on here, I know about blood spots, but I am finding "stuff" inside the eggs. I read about "meat" eggs, but this doesn't seem to match the description. I found what looked like a small stone (grit??) in one. Something that DID look like a chunk of meat (not a spot) in another and today what looked like a small twig! It was hard and I was able to dig it out but it broke the yolk to do so. My eggs could be fertile, but I collect and refrigerate every day. What do I tell my customers if they find this stuff?
