We have about 30 pullets about 3 days old.. different breeds but the majority are either black australorp or araucanas ... everyone has been getting along just fine except for one of my black australorps has gone crazy!! She literally attacks the others pecking them and pulling them around or grabbing them by their beaks and throwing them on their backs... I dont know what to do...mind you they are all only about 3 days old... is this just a normal pecking order behavior or is she attacking all the others bc she is mean??? Im so confused... HELP! I DONT want any of my babies hurt over her.
