Ok, so the coop is 32 sq feet so technically 8 standard chickens. By adding the poop shelf I gain a second layer of about 16 sq. feet. So here is the math. If I close the area under the shelf off for storage I only have 16 sq feet of floor space but the coop is 32 sq feet, or if I leave it open is it now equivalent to 48 square feet. Or is it still just a 32 sq ft coop with only 16 or 32 sq ft of flor space?
