Thank you for responding, I spent the biggest part of the day watching them. It is the other chickens doing it. It is like a mob mentality, once blood is drawn they all attack. I had to separate the injuried one today. I went ahead and just let them out to free range, they are big enough just left plenty of hiding boxes for them. This seemed to calm everyone down. They were doing thier normal pecking order arguements, but once injured I guess they dramatically fell to the bottom of the whole ladder. Perhaps now they have more room to roam and chase bugs, they wont worry about each other as much. The older hens checked them out and went on their way, so no problem with the bigger ones.
