What is the best way or what are the options of ways to mark chicks for various reasons? Maybe I want to mark chicks I think are roosters vs hens or maybe breed x over breed y... or maybe I want to mark one that one of my kids gave a name to already. In any case, how can I do it? Paint on their leg? Toenail polish? I'd prefer something I can make at home... don't feel like ordering specialized leg bands (which I'm sure must exist).
