i just received 10 cayuga ducklings from McMurray. I am keeping three and selling the rest and I wanted to mark the three that i purchased for myself. The three that were sexed have little bands on their ankles that need to come off in the next few days so i want to mark them. Anyone know of a safe way to do that? oh and if anyone can tell me how to post a picture on here I would love to show you my babies! Thanks!
