@countrytom72 I figured I would get a comment like this eventually so I wanted to kindly share why I ended up marking with ink. I used to mark in pencil or crayon and the problem with both is the mark won't last 3 weeks in a humid incubator. Additionally, I discovered through candling that pencil sometimes scratches the egg. I did a side by side experimental hatch with pencil vs marker. Same chickens. Same incubator and the marker eggs had higher hatch rates. Ink has never affected my hatches.
Writing on eggs with a permament marker is a big NO NO it penetrates the shell and membrane
