John: you would get a kick out of the rooster. And free ranging becomes much safer for your hens not to mention the beauty those roosters add to your yard. I m not entirely sure how one should go about introducing a lad to your lasses as my roo grew up with his girls. It can be done though I'm sure. The trick tho is finding one that is good to you as well. As your girls. I would not tolerate a mean one. Where I live there are always roosters in the for sale pages or animal activists who are saving roosters; " re socializing" them if needed and letting them out for adoption for nearly nothing. A rooster would work perfectly on your set up there. It might take your girls some adjustment to him too.
