Cool post I love these step-by-step posts. I'm interested with how you use your second tunnel too. We have a lot of wild turkeys here and the mothers are herding around their broods right now. There is a group of 4 moms and about 15 little ones. When they go through in the morning I always think of your chicken tractor haha The moms kick up a lot of stuff for the little ones. They seem to over emphasize the scratching either teaching or kicking up stuff for the young ones.
