my daughter has her first batch of eggs in the bator. we ended up with 7 fertile eggs. we have a couple of questions. it is now day 20 and we really do not know what to do. ew added water on day 19 when we removed the automatic egg turner. now what? just wait till they hatch? what if some hatch before the others? how long do you leave them in there after they hatch? we kinda need some guidance to get us through the end of this. thank you for your help.
