once my chickens are grown, I will buy little identifying tag things, the little "bracelets" for their leg. But for now, since i Dont feel like going to the store and dont want to have to re-fit the bracelets....can I use sharpie marker on a tail or wing feather? My girls are 3-4 weeks old. How long will the marker last and when do they-chicks, not sharpies- molt?
