Oh ok, It's called an open air coop or tractor. The use them a lot in the south because there is nicer weather all year long. In the northern areas, it is sometimes better to have a completely draft free closed coop so that the wind does not cause them to get frostbite, and they can stay in there during heavy snow. The only thing I would suggest is to completely cover that one half open side with tin. That way the have full coverage on 3 sides, just in case it starts raining sideways. Also, if possible, change out the chicken wire for either welded wire, or better yet, hardware cloth. Chicken wire does nothing but keep them in. Any creature can rip right through it.
If you are in the north, you might want to consider just closing the front off too, to make an enclosed room for them.
