So far they have 8 out of one batch of 16 hatch in one room ..all but one has cracks in it... and 2, almost 3 out of the second batch...in the other room; several have cracks in it.. Now, anythingi super important I should tell them when I go up? I'll get pics..of course they are all (the kids) wanting to know if they are girls/boys..lol and what kinds they are (teachers) I have NO clue lol.. but since the teachers go home at afternoon..I know one teacher will go back up to ck on them later this eve..but if any hatch late tonight are they ok to stay in the incubator overnight til the morning again? Or does she really need to come up every few hrs? I'm leaving in 1/2 hr..so I hope I get answers before then..sorry for the late posting!! TIA!
