Back before I knew about toe punches etc. I learned that with chicks that they outgrew most things too fast. You really have to stay on top of it. The temporary marks are just that. Temporary.
Really it is best to take the time and purchase a toe punch and learn the process. Just monitor and re punch as necessary. Or do as one poster does and cuts the webs. I realize some might have some aversion to doing these things, but neither does method does the birds no real harm. The identification is permanent. When they are ready, put some colored bands on them.
What I have an aversion to is losing their identification, or leg bands cutting into their legs.
This would seem the simplest, permanent solution; costing nothing more than the few dollars for sharp manicure scissors.
