This is an interesting idea. So basically the second run is like a protected "pasture". You say 500 sq ft total, how is that split between the two runs?
Main run is 10x20 minus the space the coop takes up (it's in the center). Second run is 17x20 with 2 garden beds that may or may not be fenced off, depending on season.
This is an old photo back when both sides still had grass. About 40% remains on the left side now. With winter on the way that grass will get more time to recover, all the way through rainy start of spring.
