Think about how you will do lockdown if you set eggs on multiple days. I have found a 5 day space is needed between multiple set dates as sometimes hatching takes a bit longer and then the hatcher incubator still has to be cleaned and reset up. If you are planning to set and hatch in the same incubator, then the question becomes when to raise the humidity level and how long any early hatches might have to stay in the incubator until that last egg hatches.
I'm not saying it can't be done but that having a plan of action greatly helps the "stress" of lockdown time for you.
