I have a Brinsea Maxi ii Advance & this is my first time using it. One duck has hatched & is all fluffed up. It is day 28. He/she appears to be about 24 hours ahead of the rest of the eggs (the others have only just now externally pipped). Is it okay to leave him/her in the incubator for another 24-48 hours while the others finish hatching? I don't want to open the lid but does he/she need to come out or can he/she stay in there at least until all the eggs have all zipped? Is it too hot in there for one who is ready for the brooder? Does he/she need a drink? How long can he/she safely stay in there? He/she seems ready to come out now but I don't want to open the lid.?!?!?!
