I've got about 20 eggs in the incubator. ( ) But Im the type who has PET chickens, and like to keep a file for their birthday, color, and any other extra stuff. SO. My question is, what can I put on the chicks to tell them apart when they hatch? I certainly can't keep a file on them when I don't know who is who. I've read a bunch of stuff that you can put on them but don't want them pecking and picking at each others feet (leg bands). Any ideas? thanks.
