Just curious here, does anyone know if opossums will attack and kill poultry if they have access to an alternate food source? I ask because we have had a family of Opossums living in our barn for the past 10 years or so. We see them every year and have seen them with babies on occasion. They have lived peacefully with our cats, chickens, guineas, turkey and peacocks. We believe in a live and let live philosophy and so long as they do no harm we do none to them, if they were to start killing our birds they would be dealt with swiftly. Our chickens are completely free range roosting where they want and the opossums could easily get them if they wanted, but we've had zero deaths and zero disappearances. So why would some opossums be so bloodthirsty while others are not at all? As for the alternate food source, we put out a very big dish of hard cat food every evening, this is where we usually see our opossums...eating cat food.
Sometimes yes, sometimes no. It depends on what the opossum prefers to eat. I suspect that chasing chickens around in the trees is a lot more effort for the opossum than walking up to a bowl of cat food.
