So, I had a flock of 4 (1 orpington and 3 silkies). I then acquired 3 younger chickens (2 faverolles and 1 polish) and kept the quarantined from the older chickens until I knew they were disease-free and fully feathered. Then all 3 silkies from the older group ended up being roosters . I kept one roo and found a home for the other 2. So, I'm down to 2 older chickens who are 4 months old. The younger 3 are now 10 weeks old, and I started to integrate them to the older 2 a couple of weeks ago using the "playpen method." They all seemed to get along fine through the fence, so I began to let them free-range together. My silkie roo is doing great with the 3 new "littles" and being a sweet boy, but the older orpington pullet is being a royal b*tch to them. And she is a BIG lady. She chases and pecks (which is to be expected) but she just won't stop. The other 3 are breeds that are never going to be as big as her and I'm wondering what I can do to make her stop being such a bossy lady. I have tried holding her down to show dominance whenever she attacks them... separating her from everyone else... carrying her around with me for awhile. It's only been a few days of actually free-ranging them together.... is this normal? I am worried about the extreme size difference and her really hurting them, and I can't be there to mediate 24/7. Wait and try again in a couple of weeks? Stick it out?
