Quail hatching eggs

[Cason]

Someone posted (I can't seem to find it, imagine that!) he/she planned to "mark" the chicks that are hatched from the largest eggs. I'm not quite understanding HOW that is going to be done without opening the incubator everytime an egg hatches?

I'm one of the one that has broken the rules and opened the bator to take chicks out to avoid them rolling other eggs so I could see this possible to mark them that way otherwise im not sure how they would to it!
