We finished our coop for our three bantam easter eggers today!
The run is 3'x8' and the coop 3'x4'. The only improvement we will make is replacing the pvc coated galvanized chicken wire for hardware cloth. DH put the wire in trying to be helpful.
We do not plan to freerange as we live in a subdivision and cant risk loose birds. We do have another moveable run so they can clean out our garden beds and roam the sideyard a bit.
