Wanting to know what strange things your chickens freak out about. Found out yesterday mine are afraid of garbage can lids. My tool shed is right next to the coop. Was cleaning out the tool shed and I have a plactic garbage can and lid I keep koi food in, well as I was putting things back in and I went to lift the can the lid popped of and rolled end over end and went by the run. The chickens freaked, flying into the top netting, into the sides of the run and generally flipping out. The squawking over this "new" predator went on for a half hour.
