At last, a trick that works! I am a fancy fowl hobbyist and have had everything from owl, weasel, coyote and coons as culprits. This year I read your article in Backyard Poultry and decided to try the Nite Guard. I have not lost a single critter to predators since putting the Nite Guard in place. I highly recommend the Nite Guard. It is a great investment.
