We clearly have an opossum liviing I think between our wall and our neighbors fence. I spotted the disgusting thing today with babies hang on its back. Yuck! We cannot get traps here any longer but I guess I am allowed to hire someone to remove it from our yard. We are in SoCal in a city. How much of a threat are they to my chickens? They are still sleeping in the garage at night as they are 4 weeks old but I am worried for them when they start staying out at night. Their enclosure is secure top and sides but it is chicken wire. Could one get through that size of hole. Here is a pic. The little hen house is in there now but not pictured here.
