This may sound strange, but have you ever knocked out a chicken???? I was cleaning up sticks while they were free ranging and chunked it........ I turned around and it had hit one of my roosters in the head. It scared me to death. I had thought i killed it, but when i picked it up it started skwawking and ran aroun in circles. Thankfully he is alright...... i hope. Well just had to share my experience.
