It has been chilly here in Southeast NH so we put a heat lamp in the coop to offset those really chilly night (please don't judge). One of our three girls is all of a sudden molting or she is being pecked at by the other two. They are mainly in the coop all day as it is so cold so I wouldn't be surprised if she was being pecked at. I put clear plastic shower curtains around the enclosed run today hoping the sun would warm that area and the girls would go out for a while. It worked really well last winter. Not sure what else I can do. Any ideas??
