Yes, that worked with mine, too. Don't ever chase one or try to catch it in front of your dog, either! I did this a while ago and the dog thought that it must be OK for him to do it, too.
Tell your dog "NO" if he gets too close. That's what I did. My dog went from chasing the chickens to pretty much leaving them alone. He's pretty stubborn, too, so it took some time and a few taps on the nose, but he learned.
