I’ve heard RIR can be aggressive towards other chickens but I have no personal experienceAwesome, thank you. The lady giving them away said they were jersey giants but as soon as I saw the red I knew they weren't but the 2 black pullets have no combs and I was wondering. My RIR's are bullying them so I put feed out in different places so they can all eat. Will the bullying stop when the rooster matures?
