marking hatchlings?

OK, since most of the babies I'm expecting this year are normals (well, hets), is there some way I can mark babies indiv to tell them apart when I house different clutches together? Like nail polish or a Sharpie, but something that won't be absorbed or is harmless?
Thanks!

it would probably be best to mark the eggs and seperate the offsring so none get mixed up. I have no idea of anything used to mark geckos

I don't know what would work with leopard geckos for marking them. I know certain people used fingernail polish to mark beardies, but i just don't know about leo's since they eat their sheds. I think it would possibly harm them, but i dont know.

Lisa, I wouldn't mark them personally. I make specific notes about apperences. Such as the circle back or the dot on the butt of the ones in your pics. I also try to keep individual pics of each hatchling. The best way to keep them but not always most convenient, is to house them seperately.

A sharpie would be better, less toxic, but as they do eat their shed htey would be marked one day and not the next! It is hard to tell some of the little boogers apart!

I take pics like Jeremy mentioned and print them on index cards that are 4X6, they are like a $1 a pack of 100 cards, then on the back I can write anything that stand outs and I keep their weight info etc on the card too. As the card gets full I put the info into my herp care software and by then they are usually ready for a new pic and I attach the cards together so I can see how the baby changed.

I have only hatched 2 so Im not sure if this will be a long term good way to do this but I also did this with the 40 new adults I bought for this year so I could keep up with which one was what het since they were all het form something lol

That is really a good idea. I was going to suggest maybe doing something like a brand inspection for horses where you have an outline of the horse then draw in the specific marking for that animal, but your way sounds more effecient. Plus it is another reason to add to my growing list (trying to get Hubby to give in and buy me a digital camera )

YES, he has to buy you a digi cam!!!

I also do like Jeremy and refer to the hatchlings by a unique marking or feature. That is why my leos end up with such distinguished names as 4-Spot, V, Circlebutt, and 7 (she had 7 bands on her tail). But you do have to be sure you're picking a marking that won't disappear in the next shed! Or you will end up very confused... Not that I ever did that...

. . . but a while ago on the KS forum, I knew a person who would put marks on their cloaca - dots - to tell them apart.

Kelli - Robin, Marcia - do you remember what I'm talking about?
