First night we found a headless chicken. Didn't know what did it. Second night we heard the death cry of another hen. I went out at 2 am and found two coons helping each other get into the coop. They didn't care that I was there. I beat them away with a broom and spread ammonia and left a old tshirt soaked in ammonia. Also put a motion light in and they haven't returned. I have a .22 and crossbow by the back door waiting just in case.
