Buffs are great birds. I was going to order some with my yearly meat birds (cornish x rocks), but they wouldn't be available until late Aug. So, I ordered 6 Black Jersey Giants instead.
Maybe Scrambles just needs a spa day. I had a beat up Buff Orp that was being picked on at the tail, and was also raw on her underside. I separated her, gave her a warm bath and washed her. Put her in a pen with heat lamp and fed protein (eggs, meat). She recovered nicely. After about 3 months her wound healed and feathers all grew back. Then she was fine with the other birds. She's gone now, that's why I wanted to order more.
