I've been outside all day long working in the garage and I've checked on the chickens dozens of time. All was well. Then I heard a ruckus and thougth, there must be an egg. Well sure enough, there was an egg. However, under the nest box sprawled out was one of my SLW girls dead. I picked up her little lifeless body and noticed that her vent was all bloody. What happened? There was no blood on the egg. No blood anywhere else. They were all fine just a little bit before that, nobody acting weird. What could have killed her that fast? I'm really upset.
