The article isn't there anymore. What was it? I found one in my chicken's nest today.
Welcome To BYCIs this a "lash" egg? I found it yesterday. Although my hens have 6 laying boxes, they all lay in the same box. How do I know which hen layed it? Thanks!
Yes, it does look like a Lash Egg (Salpingitis).
You probably will not be able to tell which hen expelled the material until she begins to show symptoms or you see her expelling more material.
Here's information about Lash Egg:
