This was really gross! In choosing an egg for my banana bread, I chose the one that had darker brown at the pointy top of the egg and a lighter brown at the bottom. I figured our customers wouldn't like the way that egg looked. Thank goodness I chose that one because when I cracked it open, blood came out, and then I continued to crack it all the way and there was a yellow egg yolk with a large blood clot attached to it. I'm not sure which chicken this came from, so the breed is unknown. The age of the chickens in that coop are 1 year old. We feed them an all-natural egg layer pellet, scratch feed, and barn lime. They do not have access to the outdoor right now since we are letting the grass get established first. We recently had a chicken prolapse and then lay a rotten egg 2 weeks later. Other than these instances, we get about 100 good eggs every day, and several double yolkers. Any thoughts from other chicken farmers? What is this blood clot? We have roosters in with the hens, but we collect our eggs daily so no chance of it being a baby chicken.
