We have 6 older Rhodies and 10 new ones who get along fine, they are all in the coop together and all free range together. My 3 Banties and duck however are a different story. They are all about the same age, but whenever the Banties and duck are free ranging, my older ladies literally attack them, jump on them, peck them, gang up on them, etc. they are in a dog kennel at night right next to the Rhodies and during the day they are in an outdoor kennel so the older girls can see them then too. The older girls even peck at the outdoor kennel to try to get to them. The new ones are just about 17 weeks old now and we need to get them together but I'm scared and don't want anyone getting hurt or worse :-( please, please help!!!
