sorry thought you were talking about incubation temps. I think i remember your screen name and you were looking for an incubator. So i assumed that you were keeping eggs at those temps.
about marking...you really have to give credit to those who mark their babies like that. Trust me, its not as easy as you would think. first of all the babies are very scared that you will eat them, so it's kinda hard to catch em. and they are so small and fragile, i've always been scared of hurting them.
I've tried marking before with a Sharpie marker and it didn't leave much ink on them. I keep track of them based on the color of them.
