Another great protecter for chickens is you have more then an acre is a Llama. They will free range right beside your flock.
I would not recommend them for bear, cougars or wolves but great for coyotes, dogs, raccons, and such. I know they have been
known to stand up to mountain lions but they don't win. They look much bigger then they are. Meaning under 300 lbs. Many
of them even smaller. And they do not normally spit at humans....... mainly at each other. Spitting at humans is rare and
usually has a reason for it.
