One thing i would definitely add is shade. Never made it to nebraska but i bet you do have some hot days. As previously mentioned added ventilation. Getting out of the direct sun they will go into the coop. 55 gallon plastic barrels cut in half make good container pots. I did that and it helped. I cant post here but do have them on my album pics. The only thing chicken wire will stop is birds. Coyotes will defeat it as will other predators.
