thanks, that's what i've done -- put some additional oak branches (the scratchy kind, good for hiding in) inside the run, along with several big piles of hay/straw raked up from the field, which they love to peck through. unfortunately i only have the ONE coop henhouse inside a run), so there's nowhere to put the more aggressive ones, except to let them free-range outside, but i need to go to work & there's rain coming later today... will just hope she can learn to avoid the meanies.
edit: to answer ron's question -- the new ones are the same size as the younger flock (all 10-12ish weeks old, and there are five of them total), and they seem to be getting along with those girls no problem -- but there are 7 who are 22-23 weeks old, who are bigger.I
