Take your eggs you gather every day and place them in a cool spot (I used an old boot box with a quail egg carton in it). Store them pointy end down and tip them from one side to the other (keeping the point down) twice to three times a day. On day 7, take them out of the cool spot and move them to near your incubator along with that day's worth of eggs.
To keep them separate from the other eggs already in the 'bator, it depends on whether you are using a turner or not. If you are using a turner, use a different rack for each batch and put a piece of tape or a sticker dot with the date you set that "rack". If you are using the hand turning method, I would suggest writing the date on each one or giving it a letter, for example the first batch would have an A on them, the second a B, the third... you get the picture. This way you can keep the two batches separate from each other for lockdown.
If you are using a turner and it will work without all the rails in it, pull out two now. This gives you a "hatching zone" in the 'bator. Move the batches to this area when hatching date approaches. You can use some wire or something to separate it from the rest of the 'bator so the little ones don't get trapped under a turning rail. Since humidity needs to increase a bit during hatching, you run the risk of drowning the next batch in line but if you monitor the humidity closely and don't let it get too extremely high, the majority should be okay.
In this situation where you will be doing a batch a week until you have birds coming out your ears I would splurge and get another incubator if you are using one of the tabletop models to use as a hatcher instead of trying to do it all in one. If you have one of those multiple shelf cabinet ones, then don't worry about the paragraph above and just use one shelf per batch. As fast as Coturnix hatch (and that's just an educated guess as to your breed) I don't think you will ever need to worry about the eggs on shelf A still in the turning stage of incubating when Batch D comes along. A should already be in the brooder and chirping up a storm. Also humidity won't be as much of a problem either since humidity sinks a bit, making the lower portion of a cabinet incubator a bit more humid than the upper portions (that's why most cabinet styles have the "hatch rack" on the bottom).
