I have 4 breeds, 3 chicks each breed. I want to mark each chick so I can tell who is who. I read all the threads on banding and they were not alot of help. We tried putting a small zip tie around one of the legs last night but we were afraid to put it too tight because we will need room to cut it off after they grow some. (they're 1 week old today). The chick walk around funny for a while (it was very funny LOL) and then shook the zip tie off. We don't feel comfortable with using the zip ties on them while they are growing so is there any other way to mark them safely. I only need to use three different colors since I can tell the different breeds apart. Can I paint their toes somehow??? Fingernail polish?? Magic marker?? What about food coloring on their backs? Magic marker on back?? It doesn't have to be permanent....just want to know who's who while they are growing. Please, all suggestions on what is safe and works. Thanks so much.
