Yesterday when I was collecting eggs from the hen house I noticed blood sprinkled in their normal walk path, I thought it was just minor. This morning I went out and a lot more blood everywhere. So I started scanning for any of my birds to have an injury, then I spotted my Penedesenca hen with what it seemed like her vent exploded. Very gruesome looking with manure caked on what was hanging out. I knew she was in to bad of shape to recover so I used the .22 to take her out of her pain. What would of caused this? I think she must of been egg bound cause she hasn't laid in 4 days. Is there a way to prevent it from happening again? Or is it just mother nature doing a dirty deed.
