I store my feed and scratch in these containers. They have round, screw-on lids that must be turned several times to remove them. The rubbermaid container is empty but is usually full of shavings. They are kept just outside the garage door, next to the woodpile. (Excuse the mess. DH is hooking electricity to the spa.) I went out this morning to fill a feeder and found the container on the right laying on the ground, the lid was off and feed was spilled everywhere. I picked it up and put the lid back on and noticed bite or claw marks around the edge of the lid. I always put the lid back on and tighten it, and hubby never feeds the chickens so I know the lid was not left off. What am I dealing with? We live at about 1800 ft elevation just above Auburn, CA. Raccoons? Bears? I guess that is silly, a bear would have just ripped the lid off. I am going to move the containers inside the garage permanently but I am going to leave them outside tonight. I will set up my game camera and try to find out what wicked thing lurks on my back porch. Thanks for looking!
