Staggered hatches aren't optimal conditions, but yes it can be done. Ridge runner has explained the biggest reasons it's a pain in the butt, and the problems that result from staggered hatches. They are more doable if there are a couple weeks in between so moisture loss can be evened out. My last three hatches were staggered, by 2 weeks. I never recommend putting eggs in daily or weekly without a second incubator as a hatcher. However, if needs be, two weeks between them is doable with more success. My tips for this is make sure your humidity is up for hatch if you are turning the other eggs, never leave automatic turners in during hatch. Watch your air cells to make sure later hatches loose enough moisture. After the initial hatch, drop humidity and run dry until you know the air cells are where they need to be.
Best way to do staggered hatches is definitely to have a second incubator, especially if it's going to be a routine.But it can be done.
