We are in the process of designing our coop and have some questions. We have 4 buffs and will be adding 2 easter eggers next year for a total of 6. Does the 4 sqft per bird include the nesting boxes? What is the sqft needed for the run? As much as I would love to free range them there are just to many preditors around. Is 3 nesting boxes going to be enough for 6 birds or should we have 4? Thanks for your help! Christina
