I am fairly new to Chickens ... the girls all free range by day and coop by night. This week between 3-4pm something killed one chicken (lots of feathers) and another is missing not a single feather from that chicken could be found. Other two are safe and sound and don't seem to bothered that the other two are not there! Wondering if she got lost when she ran or been taken - any thought or advice? I would be surprised if a fox or similar as there was a lot of activity around just prior to 3pm (ours dogs, kids etc.).
