My eggs have gone several days past hatch. I believe it has to do with my humidity levels. I want to open an egg and see what happened. What am I looking for exactly? I am doing this not only for my own information but for the 4-H kids in my club that are studying poultry. I don't plan to open in front of them but I am going to photo the process and let them see what went wrong - but first I need to understand it. So is there a sight with photos or something that will show me what went wrong by the way it all looks on the inside? Thanks again!
