That coop size is good for 6. Remember the run minimum is 10sqft/bird so no smaller than 60sqft. So a 6X10 would work or, using the 4ft coop wall, 4X15. If using the 8ft coop wall it would be 8X7.5 (bah, just make that one 8X8). Very exciting! So glad you are going to go with a good beginning. I hope there will be pictures!
