Yes, our tractors are open on the ground floor so they can do as a chicken naturally does: scratch and peck the ground looking for all sorts of goodies. They are also provided with shade on one half of the tractor and sun exposure on the other half. We utilize chicken tractors for a few reasons, with the biggest reason being predators. Living in a more rural area that is teeming with wildlife also means it comes with predators and prey. Most wild prey have a natural ability to go into flight mode and have a fighting chance. Meat chickens do not come with that same ability, unfortunately. In our vicinity we have aerial and land predators in all sizes that love chicken as much as we do; and after you have suffered the loss of raising them up only to lose nearly half in one 5-minute session of a pack of coyotes hunting, it seems prudent to make the choice to protect them. Chicken tractors also help with the ability to manage our chicken area a bit more. Meat chickens are not like laying hens, which like to travel more. They are more sedentary and perfectly content to move from the food and water and decide to take naps in between. They have more than enough space to all move around freely within their tractor and are provided fresh water changes three times a day, and their grain food twice a day. Because meat chickens poop a lot, A LOT, we move them once a day to give them fresh bedding and scratch area every day, until their final 1-2 weeks where they are moved morning and afternoon, which helps encourage them to move more and stay off their waste.
