I took a longer route with respect to interactions between chickens and dogs. I expect protection and use hunting dogs where their territorial nature is promoted and their prey drive with respect to chickens is subdued. The take anywhere from 18 months to 2 years to get up to speed since what is desired is not innate, rather reliant upon their abilities to learn from me, chickens and even predators. Usually more than one bird is lost in process but in the end dogs prevent a lot more losses than they cause. The dogs can detect threats directly just like dogs used for protecting sheep and goats but my dogs also read the chickens communications effectively using the flocks as a radar for detecting bad guys even when down wind and out of sight which is easy to realize on my place. Once dogs are on the job I can sleep easier at night even with birds roosting on ground in a pasture. I live in an area without leash laws so fencing helps with free-ranging dogs but fencing does not stop most wild predators except under very specific conditions that do not protect my free-ranging birds. Just before starting this post my dogs ran off two pit bulls which is not as good as it sounds. We know those dogs and I have already invested effort in one of those dogs to keep from chasing by birds. This was done in part to develop good relationship with neighbor owning dog. Those same dogs if not causing me problems inadvertently help protect my birds as well because they are hostile to dogs and even coyotes coming from farther away. We do very well against other predators in part because my dogs do not ignore the chickens except when close proximity to them.
