We have a flock of 5 all around 5 months old. One of the chickens has extreme scissor beak named Marley and on Thursday I came home to her having a severe injury from being pecked on her back by her tail. We immediately removed her from the flock and put her in a large wire dog kennel in our garage so we could treat the wound. I know ideally it would have been best to keep her with the flock, but due to the injury and the build of our coop it wasn't possible. I truly believed that it was one particular chicken named Butterscotch, therefore today we secluded Butterscotch and put Marley in the run with the other four chickens as we supervised. Immediately all three began pecking her and chasing her. We have decided that since she can't defend herself we are going to build an identical coop on the other end of the run and put a piece of chain link fence in the middle so she can socialize without being injured. My question is, will she be happy living in the coop alone and socializing in the run; or should we try to get a younger bird to live in her new coop with her? Marley is unable to bully because she can't peck, therefore I though had a pullet, Marley may be the dominant chicken and they could live/grow together. We live in Northern Maine and it gets very cold, therefore not sure how much she'll frequent the run in the winter. (We do plan to put a poly see through roof on the run this winter and close up the sides with either tarps, plastic, etc.) Please see the picture below of our current coop/run, we plan to put the identical coop at the opposite end.
