I'll keep you updated. According to everything I've read, free-ranging is one of the easiest and best ways to introduce new birds to each other. There's plenty to keep them pre-occupied, but yet they're aware of each other's presence. There's no dispute about territory since it's on open and mutual ground, and they gradually get used to each other with little to no fighting. It might take the roos a little longer, but I'm sure they'll come around.I hope you keep reporting on this. I was just thinking about this for my birds - I have separate flocks with separate roosters, but would love to be able to let them roam together during the day (there's a lot of fencing to keep up in the individual paddocks...)
