First flock we had, about 13 years ago, were getting slaughtered by dogs. The last round, they were completely slaughtered. Those dogs were still in the barn, and we crated them up and took them to the pound. The sheriff (we too are outside city limits, Johnson cnty, about 15 miles from Burleson) said SSS. They didn't even take a report the first time they were called out, a month before the slaughterfest, when I followed a dog up the street with one of my birds
in it's mouth. The people at that home said "not my dog".
I would strongly suggest: 1. Lock down for your birds. 2. Shoot - to injure, if you want, aim for the hindquarters - a nice sting might make the dog think twice. Air rifle (CTD has good prices) or BB. Maybe not, but it's worth a try. It is working for us, so far, when dogs come down from the hill through the creek onto our land now. We use a 22 long rifle with Aquilla rounds - no gunpowder, so you can't hear them fire. We don't hit them, just the foliage behind them, and they tuck tail and run. 3. Go to
TSC and get live traps, and take them to the pound. 4. Shoot to Kill. Shovel it under. Shut up about it, or say "gosh, gee, it was so aggressive, and we DO have rabies in the area" (no,
really - we
do - no lie).
My heart breaks for your loss. I too, if you took it to court (good luck, there) would ask for the loss of all the eggs never to be laid. Take an average of your laying record, and use that as evidence of financial loss.
