It depends. Coyotes can be attracted to any available food source. If your chickens are unattended and wandering, it is possible that coyotes will seek them as a food source. However, with secure, all-sided fencing (must have wire top and extend into the ground), the coyotes (as well as other predators) should learn that chickens are not a food source because they never get the chance to prey on the animals. This answer, however, is based on opinion and not fact; we have no research data to prove or disprove whether coyote conflicts will arise as a result of keeping chickens on your property.
