Congrats. How exciting it must be. I will never experience hatching babies, not that I wouldn't love to, but it's always nice to see everyone else's. They look beautiful.
What occurs when they FIRST come out of the shell? Do they move very much? I know there's a yolk sack process and what you have to do. I am wondering what there first thing is?
Congrats! What I'd recommend at this stage is to spray them off with warm water, making sure their sack is especially clean. Then move them into a container with a clean, warm, moist, wash cloth and keep them in that in the incubator. This will keep their sack clean and healthy till they are ready to come out of the incubator.
