I have had something get in and kill 2 ducks and 2 geese already this winter. In 3 cases the head and neck were eaten( brain and everything) and in one case the whole bird was ate. We had a mink/weasel problem about 4 years ago but havnt had one since. I believe it is a mink/weasel this time too but someone told me it could be a fox. I have lots of free ranging chickens but the geese and ducks are kept in pasture. How do I trap/kill a mink or fox without trapping one of my birds?
