Do your chickens come running to you for treats? If so, it's easy to train them to go back into their coop. You could try free ranging when you, kids, dogs, etc. are outside and then lock them up when you go back inside.
The definitely do. The minute I step outside they flock to the closest area of their run to get close to me and jump on me when I get in the run. What about fences? I have a 6' fence with spikey tops (nothing they can sit on) but all of the neighbors except one have dogs.
