I have hatched in the incubator and have let hens hatch eggs for me and also put eggs under a broody the first few days then moved them to the incubator which seems to have been the best way of all. The eggs get a terrific/natural start and they end up in a safer environment (no mishaps in the coop, etc) so I'm not a total novice. That said, I ordered a dozen hatching eggs, got 4 extra. I have one broody hen right now. I'd love to start them all under this hen but it's too many at one time. These are fresh eggs, would it be too risky to put half under her 5 days, remove them to the incubator and put the other half under her for a week ? I don't mind the dual hatching dates but I don't want to risk the second set either.
