Not without wing clipping
My run is about 4 ft high. If you clip the feathers on one wing of each bird it will help.
Make sure there is no blood in the shaft of the feather (Image below) before you clip or your bird may bleed to death.
On some birds you may even have to clip a few secondary flight feathers.
One wing throws the bird off balance and is more effective than trimming equal amounts off both wings.
