I have raised broilers in a cooop for years, but I would like to try them in a chicken ttractor now. However, we have lots of racoons in our area. The tractor will not always be on level ground and I am concerned racoons will dig under the tractor to get in. With 20 broilers, I don't want to risk that. Does anyone know an easy way to ensure racoons will not get under? I have heard of people setting up an electric fence around, but that seems liek a lot of work to set up a fence every time I move the tractor. Any ideas out there?
