Does anyone have a good suggestion for how to mark a chick for identification? I don't have a toe punch. Would using a Sharpie marker on a toe hurt the chick? I thought of painting a toenail but I'm not sure I can keep them still long enough for it to dry. I'm asking because I have 12 speckled sussex chicks that look a lot alike. I want to keep track of the progress of the one that hatched first and one I had to help. Thanks in advance!
