A grey fox just crossed the fence in daylight and ended the life of one of my five chickens . They skulked and I went out and he was still right there in the area. He apparently jumped the fence. I got the other 4 insude their safe area and put the dead one inside my shed. About 1/2 hour later they were stalking again and I saw him out there near the fence. Then he ran away. Meanwhile I have accrued a trap and put a piece of the dead one inside as bait. What else should I do? I’m planning to keep the other four sisters inside as they are plenty shook up. Anything else?
