Update: everyone is getting along we'll now. Call me crazy, but I think it may have be hormones since she started laying shortly after her poor behavior and has returned to a nice girl now.
We have 2 barred rock hens. They are 4 months old. One of them is a bullly and likes picking on her sister, our family and even our very patient golden retriever. Does anyone have any insight or suggestions on how to correct her behavoir?????
