Not that this helps, or maybe it does, but I have an almost ten year old Blue Merle collie who is fantastic around my chickens and indoor birds. His relatives, owned by his breeder, are also great around chickens. They love to herd them into the coop at night. His mother used to take great interest, in a motherly sort of way, when the baby chicks were under the heat lamp. She considered them her babies and acted as their protector.
But this particular line was bred for intelligence and working ability. Translate as a very smart , good looking dogs with lots of energy that can still do the job collies were bred to do and then some; just like Lassie. Unfortunately some collie breeders are now more interested in the show ring and breed for looks not intelligence. Sorry to say but some of those dogs couldn't herd an ant let alone a flock of sheep.
