As of last night (day 21 yesterday) I have 17 chicks (one still had a health issue going on). #18 is trying to hatch this morning and there are still 12 eggs in the incubator. No pips.... How long do I keep them in? 3 were iffy to begin with, but the others looked great via candling right before lock down... What do I do with them after "the last day"?? Do I try to open in incubator after the final wait?
