I decided to wait until I was outside most of the day to try out the chicken tractor, just in case something didn't work as planned. There are 2 doors to connect the tractor to the henhouse. There is a door that slides up to let them out of the henhouse and a door on the tractor that drops down and acts as a ramp from the henhouse into the tractor. Both can be closed so the units are individually standalone.
So Saturday, I opened both doors and sat at the far end of the chicken tractor with my trusty camera in hand to watch the grand entrance and see who would take the first walk down the ramp.
