This is a article from the magazine Backyard Poultry By: Brandon Mitchell from Tennessee.

                                                 3  DISPOSITION
Considering the space you may have your birds in, disposition is key to keeping birds healthy. Birds that are loose, flighty or even aggressive survive longer than more docile chickens like Buff Orpingtons.But trying to catch Orpingtons is a much easier task than Brown Leghorns.
            When you crowd birds, like is the case in a small coop or moveable pen, aggressive tendencies result in more injuries, infections, broken eggs, and even dead chickens, so consider this before you put aggressive breeds in with overly docile ones. If you particularly like your docile chickens, it may be best to keep them separated. At the very least, leave out all but one rooster to eliminate fighting.
