As stated previously, each chicken can be quite different. I had a Buff Orpington who was a total sweetheart and a Lavender Orpington who started out sweet but changed when she moved up the pecking order. The Lavender got so mean she actually grew spurs! Big ones! She terrorized the newest members of the flock to the point that I had to find her a new home. The relief from the entire remaining flock was palatable and immediate. One other trait of Orpingtons is that can tend to be broody. My Buff went broody several times a year where as my Lavender never went broody. None of the other hens in the mixed flock ever went broody. Since you can't have roosters, you might want to also take that into consideration.Are all varieties of Orpingtons friendly and docile? I realize all individuals are different but as a whole? I think the Lavender Orpingtons are so beautifuland we are looking at getting 3 with 3 Buffs.
