I am a beginner with raising chickens. We had a Rhode Island Red rooster and hen. Our hen was murdered last week because our neighbor doesn't keep her dogs from coming into our yard. I was heartbroken. A friend of ours couldn't stand me upset over this any longer and gave us two RIR hens. We put them in the coop but "Ed Earl" won't let them come out. When will they start getting along? Did we do the introduction incorrectly?
