had oppossums that i raised as orphans, living with a half bobcat half feral cat, in my coop, and never were trouble, just seemed to get crowded around by the hens P.S. possums can carry bacterial infections by bite and feces, but if clean, they are no trouble, as body temp to low to carry other harmful diseases that cats and coons carry most of small pests and preds). on the other hand adorable coons killed the pair and other oppossums for sport, and when food got low in area suddenly ( my neighbor suddenly stopped leaving all you can eat ca food feeders out for just them, and they turned mean, but to fat still to climb or run for monthes). nothing is odd and funnier than seeing baby oppossums suddenly carried out, around, them brooded by your hens cat, or dogs. if the oppossums started fighting or made any trouble they were dispatched or sent packing by cat or dogs though. usually they would eat the dog's food same as other supposed dangerous animals and just grow up and wander off on own when mature. only had one raccoon orphan that was nice enough that was allowed to stick around, then it just wandered off slowly over time, but found dead by fence torn up by other coons later like oppossums and cats.
