I've never used wing bands before but would like some sort of identification that (more than likely) will not come off. It will be a way to correctly identify each bird I've ever had from a chick. 1. Where do you get them? 2. Can you use lamb ear tags? 3. Is there a special tool you need to use in order to put them on your birds? 4. What age can you put them on your chicks? 5. Can you put wing bands on your older birds? 6. To remove, do you just use wire cutters? 7. Will the hole remain and never fill in? 8. I'm assuming no lead and only stainless steel?
