I want to start letting our birds free range - I am thinking of starting by letting them out for 2-3 hours before nightfall, to see how it goes. We are on a heavily wooded Appalachian hillside, and we have raccoons & possums, but during the daylight my big fears are wandering dogs & speeding cars (my neighbor takes our mostly-empty road very fast; also, if they make it to the bottom of the hill, there's a state highway)
If anyone with more experience has advice, i'd love to hear it (no chance of getting the neighbor to slow down, though).
