The one night I forgot to close the coop. 4am a neighbors dog came over and almost got my ducks. My drake hid under the shed but his girl wasn't fast enough. She was injured as a duckling and can't run very well. But I was woken by the ruckus and got to her in time. Good thing is that she wasn't injured too bad. If I had a gun, that dog would be history. Now I can't let anyone roam freely over our 2 acres since that dog keeps jumping the fence. So everyone is in a 12x12 area. Hopefully that dog won't get into it. He better not, because I will kick him into next month! I will let neighbor know that if he is over here again, he might not make it home. Ok... done with my rant & learned my lesson that no matter what... I need to close that coop!
. I think you are well within your rights to shoot the dog if it comes back again. The blooming fox came back in our garden for several nights after it's killing spree. Needless to say it was caught several nights later and shot. Glad you have learned your lesson without any loses I wish I had.
