I picked up 5 Black Australorp hens and a BA roo last week. They are about 5 months old. When we initially got them they were in a small area in our pole building until we could get an area in the barn prepared for them. Today we moved them to the barn and I noticed ALOT of feather pulling between the hens. I bought them off the guy that runs the local feed store and he had just recently purchased them from one of his customers. I was wondering if the behavior may be produced by the added stress of being moved to so many different environments? Or are Australorps just a more aggressive breed?
