If they hatch while your at school , don't worry at all, some people keep them in the incubator for a day or so anyway.
I will, lets say if they hatch at night I leave them in till morning, and if they hatch during the day, I leave them in a few hours , until I see that they are getting more active.
When I see that they are walking around more, I then move them to a 10 gallon with paper towels, heat light, and uvb.
Make sure they get water everyday with an eye dropper, drip it on their nose , they usually will start to lick it.
As far as eating they do not eat for the first 3 or 4 days and sometimes up to 2 weeks, thats the longest I ever had one go before begining to eat. Most do eat within the first week.
Well let us know when the HAPPY event takes place, we will be waiting !
