I started with 6 pulets, 4 of which decided to be roos. All got along great as 1 flock. I rehomed 2 roos and picked up 4 more hens. All of my birds are between 6 and 9 months old. My #2 roo is everything a good roo should be to the ladies, #3 roo is very mellow and is happy just to tag along. In the coop or in their run they all get along great, no major conflicts. When I let them out to free range I have 2 of the new hens that seem to want nothing to do with the flock. They each go their seperate ways and do their own thing. They are not "driven out" they seem to like being alone. It's not hard for me to keep an eye on a flock running around, but it is hard to watch over a flock and 2 loners. I worry that my loners without my #2 roo's protection will be easy marks for predators. My question; Is there something I can do to influance my loners to join the flock when they are out n about ?
