This chicken tractor is amazing! Exactly what I've been searching for..... Unfortunately, I'm not good at building anything. However, I'd like to get the plan and have a local guy build it for me. Trying to figure out what the materials would cost. Anyone build this yet and have an estimate on materials (assuming most materials aside from the bicycle parts would be purchased new)? Your help would be so much appreciated. I've got a little homestead and do pasture rotation with my sheep and would like to easily rotate my chickens as well. This lightweight easy to move tractor is just what I've been looking for!
