Does anyone use small tractor style coop.runs for Quail? I picked up some today(My 1st ever) and wanted to build a rock solid coop pen. Thinking of pouring a small concrete slab to set the tractor run on? Maybe put a top coat of river sand on the concrete? The guy i purchased from had way larger fly pens (i will not) but all of his were on dirt, which i assume is fine as lonmg as you dont have a predator/rat problem.. any links on Quail setups? Pics welcome..thanks.
