I am getting Freedom Rangers delivered soon and would like to know if they need as much space as the regular hens? We would love to have over a dozen but if they need 3 sq feet of space we may ONLY Have a dozen due to the size of building we would need to build. They will be outside grazing most of the day in a large run so do they need a lot of space inside the coop for the little time they will live there? And how do the freedom rangers taste? Does anyone buy them?
