Hello all not sure if I am posting in the correct area. We are kinda new to chickens as of April 2019. We raised ours from Murray McMurray and sadly lost our flock of 14 to one mink 4 weeks ago. We live in Maine and love chickens and they are family and were completely devastated when that happened. Since then we bought a handmade chicken coop/run made with hardware cloth. It seems to be the fort knox of coops. We bought 5 red rangers that were about 16 weeks as of 2 weeks ago. Over the past 2 days 2 of them have developed a limp and don't walk much. Since getting them they have never perched at night. Not sure if anyone has an insight
