Hi Ya'll. We built a run attatched to an old garage to house my guinea keets until they are 12 weeks old. We will be having them totally free range since we aren't here for weeks at a time. As of now the run is fully enclosed to keep them in and predators out. When we start to free range them, should we just take the too off the 4' wide run and let them fly in to roost or should we remove the entire run?
