I have a question on chicken tractors. When you move the tractor, how do you get the chickens to move along with them? My layers are in a coop with a run and this isn't a problem. I decided to venture into meat chickens and got a small batch to try until I know what I am doing. I haven't built a tractor yet, but I have the meat chicks in a large 4 sided container (3 foot by 8 foot) in the garage. I attempted to pull this outside in the yard for the chicks to be outside for a while. They would not move when I slid the box and one got a toe pinched under the side of the container. How do you teach the chickens to move with the box so they don't get run over?
