I am brand new to chicken raising. I have 5 week old chicks. I just moved them out to their new coop. I dont have an established flock so I don't have to worry about introducing birds. There is plenty of space. I know they are very nervous because of being in a totally new environment but they are fighting like never before. Should I do something? Is this normal? I know pecking order but they are fighting like cocks fight (and supposedly they are all pullets!)
