bobcat

heard a commotion from the ducks while we were eating dinner tonight.  ran outside and interrupted a bobcat attack just a little too late.  the cat came right up into the yard near the front door and was able to grab one of the ducks before i got there.  guess i spooked her though.  saw her running off into the woods as i came out and found a badly injured duck at the edge of the front yard maybe 20ft from the front door.  the duckling's back was broken but she was still alive.  i had to finish what the bobcat started. 
got the ducks into the kitchen garden, rounded up the cats and got them into their room, moved the chickens from their run into in their tractor. 
lesson learned.  i am sorry, my ducks.
