tonight we went out to feed our 4 peking ducks (2 female & 2 males) & found one male dead. not only was it dead, but most of the flesh on its neck was gone, & alot of the head was mangled & partly ate. our other 3 ducks were covered in blood.( Alot of blood on there heads & neck) & seemed a bit in shock. our other male seemed to weak to get in his pool after we put new water in it, he tried but couldnt. but anyway, we thought at first maybe the 3 other ducks attacked him, but the more research i read it seems it may have been a weasel or a mink. does anyway, have any ideas. so praying it wasnt the ducks turning on each other, we locked them in there coop & set a trap hoping to catch whatever did this.
