yeah I'd hit them for at LEAST $200, I am pretty sure a small claims court will allow loss of future income.
yesterday my neighbors (across the road) two older dogs found my chicken coop. They can't get in, but they were pacing the run barking and had the chickens all tore up. Most of them just went in the coop. I went out and ran the dogs off. They haven't been back, but it's just a matter of time. They can't get to the chickens, but they'll sure upset em. I guess it's time to go talk to the neighbor.......
