Brad, I have read about the pecking order thing but haven't seen it to this extreme. Of course, this is the first time I have added birds to an existing flock. The first six were raised together, four sex-links and two newly discovered white rocks. The existing flock will pick on each other and sometimes I saw some bullying but they are particularly brutal to the new EEs. The EEs have to roost on different perches and cannot go to the ground without getting pecked and bitten until they retreat to a perch or the upper level. Sometimes it seems that one of the sex-links will go to a perch just to pick on them but the EEs seem to have a better advantage there. They are not able to gang up on one there. I think that's why the EEs are always on a perch. Do you think this will pass? I have read that it takes a couple of weeks for a new bird to be accepted but it is hard to watch.My sex linked where like this as well, however, they were my first. So they were at top of the pecking order and wanted to stay there. They were not very welcoming to new comers. Since they learned to cross the road from the guineas, I gave them to a coworker as I didn't want this years chickens to learn to cross the road as well. It worked, but my oldest chickens still do this to the younger birds. So from my experience it is not necessarily the breed, but rather the current pecking order.
