Maybe you should clean the eggs. I mean take all that white stuff out the cake be looking great but that's something everyone doesn't know about. But that's just chicken spurm and if they don't take that out the egg I'll just have to pass sorry but my mom teached me that I really just used to watch her cook using eggs and she'll always try her best to start to getting some of that out of her eggs
Store bought eggs are never fertilized and the white chunks are neither sperm or umbilical cord these are common mistakes but it makes sense why people would come to that conclusion.
