Someone on here told me that can happen when part of a follicle gets included with the yolk. I had an egg like that once. That's a lot of blood. Give this chicken a month or two and see how she's laying then. In the meantime, I wouldn't sell her eggs, and crack them separately to check quality before trying to use them. Nothing should actually be wrong with your chicken, it just happens sometimes. If the eggs look normal, they're fine to eat. If they look like this, you can toss it or feed it back to the hens. Any poopy, misshapen, or otherwise weird looking egg, we just feed back to the hens - it doesn't even leave the coop, we don't have to fool with it, and the hens get a tasty treat. We toss them hard into a large dog bowl, and the hens will eat all the egg plus the shell. This practice hasn't created any egg eaters in our coop.
