I have 18 chickens. 12 are older girls and are in their own coop. 6 are about 8 months old and are in their own smaller coop. I recently tried to introduce my new Roo, Steve (A Silkie - my girls are all average size) to my flock. I put him into the coop with the younger hens when they went to sleep. They woke up and he had no problems fitting in. When I left my girls out to free range, my older girls didn't like Steve so much. They ganged up on him and it was one after the other taking shots at him. He held his ground and gave it back, but when his comb got a bit of blood on it, my hubby separated them and put Steve back in the run of the smaller coop. So now, I need some advice. Do I keep trying to let him out and see how they react? Do I slowly introduce each of my older girls to Steve? Or, do I sneak him into the larger coop at night and see how that pans out? I'd appreciate any advice at this point. This is our first Roo and Steve is such a sweetie, I really want this to go well.
