Tools and setup for this are a continuous-improvement sort of thing.... Have found a 4 or 4.5-inch blunt Weitlaner retractor (eBay) to work well as a spreader with larger birds (~15 weeks rather than 8-9). Still experimenting with different removal tools but currently using a tubelike device from an old Geo. Pilling "Philadelphia" set along with 26-ga jewelry/craft wire. The 24-ga that is more common in craft stores gave a little too much resistance when pulled through the tube, which is flat and somewhat bent at one end. I hear ya on the roos!! The spring weather sure "spurs 'em into action...."
