The bad news is that I found Bootstrap dead yesterday morning. I had commented that he really had a good day on Friday and acted nearly normal. Then yesterday when I went out to do my morning chores and was in the goat/chicken shed, I remembered that he hadn't said anything to me before I went out. So I came back to the house to check on him and was shocked that he had died.
The good news is that the red paint on the styrofoam forms worked. I even found one place where the chickens had scratched at the dirt around the base of the forms to uncover the unpainted surface and had pecked at that. I covered it back up and took that as a good sign that they will not be eating any red styrofoam. Hopefully the forms are now safe until we can get them covered properly.
