I'm getting rather angry! I have three jack Russell terriers and 30 chickens. Have had 4 casualties since I started raising them. I got my first ones in march. And I can't name the close calls or how many times my dogs have pursued them and I have shouted and they've thankfully listened to me. I know it's the breed. I've shown my dogs, done lure coursing, etc. They love the game of chasing and catching and well...killing. But it's down right ANnoying!!! Like just now when I open the coop door with the water bucket in my arms and the smallest chick runs between my legs. Of course I put the water container down and catch the chick. My dogs chase the smallest ones before the big ones! And in a split second I have 15 chickens in my backyard loose with my 3 dogs. At this point my eye is twitching as my barred rocks wiggle their butts and run off to play in the grass (they are always the first to bust out the door!!!) and I calmly get my dogs inside after I close the coop door (before my pheasants get out...because I will never catch them. They're still chicks and camouflage in the woods) So now I am typing and can see a bunch of flashy bad hens and young Roos spitefully enjoying my backyard and they don't seem to realize they could have triggered a massacre with one wrong move just a few minutes ago! Agh! Almost at the point where I want to rehome 2 of the 3 terriers but I also think in the perspective I am a military wife. I might be sent somewhere eventually where no chickens can go and I will be happy to have my 3 devilish dogs.
