We have only owned chickens for 4 months now. At the beginning of April we adopted our dog, Loretta, and brought her back to the farm. She never seemed to show interest in our flock. She chased after them once to see them all disburse but we sternly told her NO and she stopped after that. Well...We are musicians and we sometimes have to go out of town for performances (not nearly as much now that we are homesteading). We were gone for one day and night. We had our neighbor watching our animals, as he has done many times before. The only difference is that the dogs were left outside unattended during the day for the first time ever. (Put inside over night to sleep). We left Saturday morning and when we got back Sunday afternoon our flock was dead. There are only two remaining hens and we are sure one of the two won't last long...she is definitely in shock. Our neighbor said he saw them Saturday night so she would have had to take out 2/3 of our flock within hours. Being new to owning chickens...and dogs and definitely both at the same time, we had NO IDEA what happened. We thought they all had some weird disease and just dropped dead all in a 1foot span of each other. But after reading A LOT we realized one of our dogs had to of done it. Well...today Emerson (my boyfriend) saw her get the very scared chicken and shake the poor hen back and fourth. Luckily, she lived (SOMEHOW). We don't want to have to get rid of Loretta...she is such a wonderful dog. She is very sweet and is a smart dog. She is about 2 and we adopted her from the shelter. Her and our other dog Hank are very good friends now. We have ducks that roam the yard and, although she hasn't shown any interest in them, we are nervous because she didn't show interest in our chickens until we were gone and nobody was there to stop her. Any advice is SO appreciated! I have read and had people tell me that a shock collar could help since she is older - apparently it might help while also training her? As horrible as it is to say, I was only pretty attached to our rooster. I am definitely sad that our chickens are gone....it didn't hit me until today when i looked out the window and didn't see them clucking around Our rooster was SO great and had such a great way about him. Some days, when I would wake up a little late, he would hop over the fence and meet me at the feed can and then walk back to the coop with me to his ladies. Thinking of them make me sad and I hope they didn't feel pain when they died. Anyways, my first ever post is getting long. I'm glad to be part of this community. THANK YALL! Sincerely, A new homesteader, Earth lover, and fur-mom to a mass murderer dog. PS)Loretta is also a digger, which is how she got to our flock. If you have ANY advice of digging dogs, that is also appreciated!
