Keep an eye out on them as whoever laid it could have an infection. That doesn't really look like a lash egg but regardless whatever it is, it came out of a hen, and that means one of them most likely has an infection of their oviduct called salpingitis. She might need antibiotics.Any idea what this is? Discovered it the other morning when I went to check for eggs (our four remaining big girls are still on strike). Don’t know what to think of this.
