What’s up with this egg?

[FunClucks]

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.

There is a list of possible causes after this, but I think just the rupture of a blood vessel (a "mechanical" injury) is what happened here.

Sounds about right. Eggs from new layers can have all sorts of weird glitches, and even with regular layers I've gotten some bloody eggs like this (which is why it's best to open eggs into a cup one at a time, instead of directly into a mixing bowl). I'd chalk this up to a one off unless it happens repeatedly.

A-ha! This is the one I was thinking of: https://www.backyardchickens.com/articles/common-egg-quality-problems.65923/ (overall article)

Thank you so much. Going over the cause list nothing seems as if it fits my situation. I hope it’s just a mechanical injury as you suspect.
