Hello! I have a question you all probably get often, regarding mice. There was a rodent problem when I bought this place, but I have a cat, and keep feed in metal bins. I thought I could starve them out. Not so, because now they eat my chickens feathers

I have tried traps, ratX and now even a poison that doesn't have much of a second life(?) so I don't worry as much about a cat or chicken eating a dieing rodent..so: if I spray a solution of essential oils on their feathers, would that work? Please and thank you!
