I have had an open top duck pen for a year now and have not lost one to a raccoon or opossum. We did lose two to a fox which the ducks escaped at night and were eaten. Our raccoons and opossums usually hang out at our back porch eating cat food. I trap them and relocate them. Our chicken pen is totally enclosed but I haven’t gotten around to enclosing duck pen. Try what works best for you. Maybe put out some cat food to distract them lol
