I had my motion light click on and then the head of a coon peeked into my patio door. So my guess was he was following the chicks to see if he could get a chicken dinner. Obviously the light didn't bother him==just made it easier to see what he was looking for. I think it is a coon getting my chicks cause something pulled the staples out of the wire and drug off my last banty rooster. Shoulda had a slat over the wire and staples is my guess.
Doesn't this little pen look sweet in my little secret garden with the flowers? The motion light kicking on and off all night probably drives the momma nuts but you gotta do what you gotta do to keep the little ones safe.
