4 weeks ago I had 2 hens killed by an unknown predator. My 5 birds had been ranging uneventfully for months when they were attacked by an unknown predator about 15 minutes before they were to go in the coop for the night. My coop is inside the run and the run is enclosed. When inside they are safe. They will not leave the coop except to feed and only when I stay in the run with them. So for 3 hours a day morning noon and late afternoon I sit them. I guess from what Im seeing the Rooster with hens in tow head for the coop at even the sound of a crow or some other bird, barking dog and sometimes at the sound of nothing. I had one day where they came out to range 2 weeks ago and spent the day hiding. It was such a pleasure to watch them head out everyday in search of goodies and had a routine that you could set your watch by. Im thinking I need to add another Rooster and a couple of new hens to break the patten that has developed. Seeing them stay in the coop roosting all day safe and sound isnt like the fearless flock they once were. Its sad. They seem physically healthy but need a good therapist. I talk to them when I go in with them but Im not getting the message across I wont leave them alone again outside. What should I do/ I cant move into the coop.
