Liza the LGD (livestock guardian dog) and SL Wyandotte rooster have a good working relationship. They collaborate daily to help keep the barnyard citizens safe. When danger threatens, Liza goes after the intruder, barking wildly. SLW, growling chickenspeak commands, gets the girls to safety and then returns to back Liza up, ready to add his sharp spurs and beak to her tooth and nails defence.
Almost always, the intruder is airborne, so neither of our devoted barnyard guards has to resort to hand to hand combat. Thank goodness.
