Could these rats kill ducks? In my peacock pen I temporarily had put 3 ducks and something killed only the ducks In the pen... There was no signs of anything Getting into the pen only some rats holes Under an old dog house. We live in an orchard So wolf rats are not uncommon. Could and Would these types rats kill ducks?? One was a Muscovy so the ducks were not small and Whatever got them ate at their necks and eyes.. The peas and guineas were not harmed and saw no other signs except The rat holes???
