Will possums bother chickens during the day or just at night? We had seen possums before we had chickens, but we have a LARGE one my husband saw on the back porch a couple of weeks ago in the middle of the night. Last night night when I went to close up the run (a little late) it was about 15' away from the run in the yard! After a stare down (and me being scared to death it would "charge" at me ) it trotted away--probably living behind our shed. I usually let the chickens out of the run to have free time in the yard from around 4:00 pm to around 8:00 pm....do we have a problem before it gets dark? Does the dog need to stay out there with them when they are in the yard? The "girls" are part family & I just want to make sure they are as safe as possible.
