They are through and through bent over the top and bottom forward aspect of right wing above the ''elbow''. I bought them at a farm supply store with no info. I originaly thought they were paper to mark sex of chicks but when I got them home and released them found they were metal and seem impossible to remove without injury. It's to late to call store but plan to in morn. thanks for the help.
Is it for identification purposes? My cockatiels all had metal bands on their foot, its to track their breeder but I have never heard of (or even know why you would) doing that in chicks. Where is it located at on the wing?
