About 10 days ago one of my chickens died. It was fine in the morning, even laid an egg, and when I got there in the evening it could barely walk. It died the same night. About 2 days after, I saw a snake around my chicken coop which I could only chase of. The next day I was sitting on my porch after dark when I heard my chickens making a lot of noise. When I got there, they were all out of their coop, but I couldn't see why, and I was actually a little scared to check for any signs of a snake. These things scare me They do not want to go back in their coop at night ever since. I caught a pretty long rat snake today. I am wondering if the snake scared them out of the coop, and how do I get them to go back in at night?
