Thanks for the advice, ValerieJ! I forgot to mention that we did try that. We kept Raven in a separate pen in the garage for a week when she was being aggressive towards Sunshine. It didn't help, though. We have two feeders (one twenty pound one with two openings and a smaller one from when they were chicks that Sunshine eats from), two waterers (a two gallon one with two cups to drink from and a small bowl (refilled each day) in Sunshine's pen). There is also a small cage thing that hangs in the large pen. This is occasionally filled with treats like broccoli, brussels sprouts, squash, pepper heads, or small pieces of corn. Whenever we offer treats outside the runs, we try to do so in two or three different locations. They have two separate runs that are totally enclosed. The large one (for Dottie and Jojo) is eight feet long and almost three feet wide (about 24 square feet) It has a peaked roof that is 42 inches high at the highest point. Sunshine's is a little less than half that. (I'm not sure of the exact dimensions.) There are roosts in both coops and one in each run. They are let out for several hours almost every day when I get home. During this time they are in a larger run that is not totally enclosed. It takes up the entire space beneath a very large pine. It is just dirt, but they have a swing (that they never use), a small structure of stacked bricks to climb on, and a piece of concrete pipe. Sometimes we hang up a piece of cabbage for them to peck at. As for hiding, there is the tree's trunk, the rain barrel, and behind and around the coops. Most weekends and on the occasional weekday, they will spend several hours in the side of our yard, under another pine (they love the dirt there), in our landscaping, and in the lawn, eating clover and dandelions.
