As I'm collecting my ducks eggs this spring, I'm going to want to label them by breed and which pen they came out of.
What do you use to label your eggs? Pencil, marker, crayon? Is there anything that isn't safe? If I write on a fertile egg with Sharpie, is the duckling going to hatch with three eyes and only one leg?
Just curious. I don't want to use anything that will leech any harmful chemicals through the shell.
