Hi, guys. I know recently that my hen died from eating a small piece of metal. Now, I think my naked neck and 2 barred rocks ate the same metal peices. This metal is small degree left behind from nails that have been cut in half. So it might go into their gizzard and cut it and they die. I do not want to repeat what happened yesterday. So, I need help. If there’s anything you think might help survive, please feel free to comment. Thank you.
