We had a car speed down our gravel one lane dead end street and deliberately hit a chicken. They were going about 65 mph, in a 30mph area. She was actively walking out of the street when the driver hit her, she was 2/3 the way there. We are a working farm surrounded by other working farms with no less than 30 signs saying slow down (13 are ours, 4 belong to the town, the rest the other farmers). We are going to find a solution while still allowing free roaming and put in speed bumps (town allows).
