I have an open compost bin in the backyard and possums have been visiting it. I have 4 chickens securely locked in a coop at night and I feel confident in the strength of the coop. But the possum makes me nervous. Is it better to get rid of the compost OR is it better to provide the possum with a free salad bar? My theory is that if it has open access to the compost buffet, maybe it will leave the chickens alone?? Any advice about this would be helpful please. Thanks so much.
