My stepson's dog (my grand-dog?), Aspen, is a Pit-bull/Border Collie cross. She is very loyal, very sensitive, and protective. She is a year and a half old this month. Back in early April, she found a way into our run. She killed 3, mortally wounded 2, and I stopped her before she got the last two of our six-week old chicks. Under the 5th Amendment, I won't say what I did to her when I caught her, but I seriously considered shooting her. It took two weeks before I'd even look at her. I started letting the chicks out to free-range when I was out there to keep an eye on them and she did fine the first time. The second time, I got caught up in what I was doing and left the back yard to get a tool, and a couple of minutes later I heard loud squawking. I ran back there and caught her "herding" the chicks back to the coop (or were they fleeing for their lives?). I scolded her severely and moved on with my chores. A couple of weeks have past since that scolding. I let the chicks out whenever I am home. I even forgot about them and took the family to my stepson's baseball game. No dead chickens. On Friday, my neighbor came over with his dog, and an 8 month old pup that he has been taking care of. I'm proud to say that Aspen quickly, and effectively stopped that pup from hurting any of my chickens long enough for me to put them away safely in there coop. After that, she played with the pup all evening. I am so glad that I didn't kill this dog. My stepson is very attached to her and now, so am I.
