I have a flock of seven 18 week-olds and a flock of eight 12 week-olds. I put them together for the first time about a week ago and they were shy from each other at first. The big flock would chase the small flock around but there wasn't hardly any fighting, maybe a couple pecks. Well by the end of the day they were grazing together and life was good.... I thought, "Wow, that was easy." Well, it's been a week and it seems the flocks have grown apart. They all use different waterers and feeders and don't hang out around each other. Will they eventually grow to accept each other or will this just be how they are?
