First it was my fault I had put my chickens in there run locked it then as I was walking back towards the house I noticed I left there food outside so I went back to the run and put it in there and I am guessing I closed it but didn't lock it. So roughly 3 hours later my grandma comes and yells Jenny (My dog) is trying to get at the chickens so I go outside and look around my dog is jumping on my wanting to play and I look at my chickens that normally stay in a pack and only 3/4 chickens where there the "Leader" of the pack was missing and I asked my grandma if she sees the other chicken and she says no but Jenny keeps going over there and at that point I knew she killed a chicken so as I am walking over to where my grandma pointed I see chicken claw marks and dog paw prints which indicate she was running and as I move closer my Biggest Best chicken is dead! The thing that gets me is that I've had these chickens for 2 and a half months and my dog has always been around them when they forage even when I am not watching directly and if my dog gets to close I tell her to stand back and she does she is only a Pomeranian/spaniel 1 year old only 15 pounds and she decides to have some fun and just kills a chicken! JUST KILLS IT FOR NO GOOD REASON! But like I said it's my fault so I didn't hit my dog or yell at her I calmly grabbed a rope and tied it to her for 5 hours my parents said it was to harsh but I don't think it is my dog KNOWS what she did and she knows not to go towards the chickens because I get on to her so after those 5 hours I just put her in her bed and ignored her gave her a dirty look every once and a while and hope that she learns. Sorry I just had to get that off my back I can't sleep!
