All three of my girls are at various stages of molting. The girl who was probably the most docile is now a total brute. I have 2 RIR and an EE. The EE has become really aggressive since molting. For the past week or so she has been chasing the 2 RIR girls around the coop, chasing them away from food and water. Just now we found her on top of what once was the top bird pulling out her neck feathers, pecking at her really bad and acting like she was going to kill her. She is now segregated on the top part of a 2 story coop but is pacing back and forth. She is striking out at us when we get near and trying to peck. She is even to the point of drawing blood on us. I need to know what to do and fast. This was once my most easy going girl. Just to give you some more info: This is the first time the girls molted with the RIR who was attacked laying her first egg again since she molted and she also used to be the top bird. The EE has just grown back her feathers and my other EE is looking like a porcupine right now. The coop is 2 stories with each level measuring 2ft x 8ft. We keep supplemental light on the bottom and the next box is on the top.
