Over the past 7 months, I have raised 24 guinea keets and 24 Barred Rock chicks. A neighbor refused to keep their dogs from coming to my home (1/2 mile away). These dogs killed 19 of my guineas within a short time from when they were removed from the brooder. Numerous complaints to the neighbors did no good to restrain their dogs. Although after their killng spree with my guineas, I didn't see the dogs. I decided to accept it, and got some chicks to brood. While they were in the brooder, I spent a lot of time trying to make my pen predator-proof, in spite of being semi-handicapped. Yesterday I turned my chicks loose out of the brooder (they were 12 weeks old). My chicks seemed happy, running around, scratching. This morning, I got up, looked out, three dogs inside the pen and all of my chickens are dead. I cannot figure out how the dogs got in, but they could not get out. My shotgun worked very well this morning. I will be going out in a few minutes to pull the dogs out of the pen to dispose of them and my chickens. SSS Shoot, Shovel, and Shut-up. I don't know yet if I will try again. This hurts so much.
