That is your choice. I free range mine even when I have to leave the house for a little bit. I have a really good rooster and look to him to warn the girls if there is a problem. If the cat comes after them and you can't find a girl, look up first. They are really good at trying to run for cover and flying up on things when they can't. My rooster was older when I got him and every time I let the dogs out the first 3 days I had to fish him off the roof. I had to put one of them in the coop for a night to get him to stop. I do not advise this for other dogs, mine is a rescue toy poodle that was already scared of my hens outside (not inside), but his barking made my rooster fly onto the roof.
