Dogs are naturally inclined to want to chase, play with and even kill chickens, because dogs are predators and chickens are prey. As a responsible dog owner, you can take preventive measures as well as train your dog not to engage in potentially hazardous behaviors. You can provide a relatively safe environment for all of your animals if you stay attentive and work to figure out what the best method is to keep your dog away from the chickens.
Things You'll Need
Block your dog's access to the chicken coop by whatever means or modifications are necessary. This may involve putting a door up, locking a door or gate or even adding onto your current coop so that your dog cannot climb over the fence, go through the fence or dig under it. Your first priority as a chicken owner is to stop predators from reaching your birds.
Train your dog to respond to simple commands such as sit, stay or lie down. Offer your dog a treat or praise every time he performs correctly. Work with him until he responds to you regardless of what other stimuli is in the area.
Introduce your dog to your chickens. Keep him on a leash and allow him to express interest but not chase the chickens or torment them in any way. If your dog tries to engage in predatory behavior, use the commands you have taught him to make him disengage from the chickens and focus on you. If you have trained your dog properly, he should sit, stay or lie down and leave the chickens alone. Praise him when he behaves appropriately.
