I'm gkad you covered the one side. Sun can be brutal on chickens! The roosting bars could be lower. Consider hanging a bar from the shelf and I'd bet you will catch them swinging from time to time. My chickens are playful that way. The greens are great but don't overdo. Only 15% of their diet should be green. And no potatoes, onions, caggage or asparagus as they could taint the flavor of the eggs as I found out. However, my chickens love diced garlic. I just add it to their water once or twice a month. It's good for internal parasites, as I have read so many times! Good job & good luck!
