Marking eggs???

[SamG347]

I have always used a pencil to mark my chicken and pheasant eggs when I incubate but with these cortunix being speckled with dark spots I was wondering would it be safe to use Crayola markers to mark them?

Thanks all!

I have always used pencil.
I was told that anything that might seep through the shell damages the eggs. Makes sense but I don't know if it is true.

You can use a grease pencil. They come in assorted colors, white would probally be good to see.

I'm using a white grease pencil on my Welsummer eggs. Works good!
