I noticed in the coop thread that a lot of you have chicken runs that are short in height. Looks like maybe 2-3 feet tall. How do you clean in them or get into them when needed? I'd like to relocate some of my hens to my mother's house in town so she has some chickens of her own. Her backyard is set up in a way that a tractor won't work there. It's best for her to have a completely covered run as they have foxes running around the neighborhood. The short run looks like a good idea for her, but I was worried about how to get into them if she needs to.
