Bear with me, this may seem a silly question. How do you put on the coil-type leg rings on new chicks? If you open it too wide, it loses the smooth ring shape on the interior and then irritates the leg. I tried that and had to take it off. I have chicks which I definitely need to keep identified. I bought the multiple sizes of ring leg bands for when they grow, but after yesterday's experience I'm worried about getting them on right.
