I keep a fair number of my birds in pens made in part of 2 x 4 inch welded wire. Sticks provided as roost are supported by pen walls. With the usual birds of this arrangement (American Games) they roost in middle of stick well away from walls of pen. American doms on other hand push themselves right up against pen wall. Any predator otherwise detered by fencing can simply reach through, grab bird and dismember it to consume a leasuire. Any ideas on how to keep bird away for pen wall? I was thinking about making ends of roosting stick difficult to stand on but have not tried as of yet.
