Just my luck, as soon as we culled the slightly aggressive roo, I had the funds to make a run (instead of 100% free range then my son would play outside and get flogged). Now that one of our hens got taken by a predator -- now down to 2 of 4 of my 1st flock -- I'm started to wonder if I need a roo again. I currently have 2 week old chicks (not with the hens) and I want to ensure to most peaceful transition possible. The BR hen is my Houdini. No matter what modifications I make to the run, she ALWAYS manages to get out. Every time I put her back in, the RIR hen pecks at her head and body... she can be a real bully come feeding time too! Basically I want to know if adopting a roo back into the flock will make the RIR hen stop being so mean to the other one or if my BR will end up being picked on by TWO sources instead of one. I still have no idea why she's so eager to get out! She'll even stick by the coop sometimes or go free-range; she's always been my "free bird".
