Just got my landlord's permission to build a chicken tractor, but I sold all of those before I moved. Anyone have ideas for duck tractors? I was thinking PVC would be ideal for the run's frame as it is lightweight and I could make a bigger run that way. My 6 runners are at my sister's place waiting for me to construct a new home for them. One of the girls just laid her first egg this week. I'm so excited to see those lovely duck eggs!
