Meet Rio, my 6 year old rescue border collie mix. I recently started my first flock of Chickens and I was sure that I have would to keep Rio separated from my flock at all times. Rio is a hunter and he has killed mice, snakes, squirrels, and moles on our 5 acres here in SW Washington State. He has tried to catch rabbits, but as far as I know he has not been successful. The first thing he does when we let him out is he chases all the birds out of the yard.
But he has no interested in chasing or killing our chickens. I think it is because the chicks grew up in the brooder in our living room. Rio would watch them intensively at first and especially if they ran, squawked or flap their wings, he would go on alert, but he slowly lost interest in them. He saw us hand feeding them and holding them all the time After I moved them to the new coop, he really did have any interest in them at all.
Now I can let them out of the coop and Rio just scans the rest of the property for other small animals. Nothing would get close to the flock if Rio was around. I still don't let the chicks out of the coop unsupervised as a hawk could swoop in if I turned my back for a second. But I am sure happy that I don't have to worry about my dog.
