Incubating at different times

[Pollito Pelon]

I currently have 13 eggs hatching these 2 days. I put 10 eggs on week two and I'm wondering once the 13 hatch and put more eggs should I take those 10 out and put new in or leave them and put other eggs along with them. I suspect that because of the high humidity when hatching those 10 might die or something.

Generally speaking they should be fine regarding humidity. However there are some other things to take into consideration. With the full week before the others hatch the incubator could become a point of contamination, hatching is messy and chicks start pooping pretty soon after hatch. The ones that hatch can kick the other eggs around quite a bit in a lot of incubator styles. I do staggered hatches, what I do is make a cardboard ring to surround the less developed eggs and place a paper towel under the eggs that are about to hatch, to absorb most of the egg moisture and poop. However, I usually don't stagger them quite that far apart, usually just a couple days.
If you take out the eggs what would you do with them?

Thanks in that case it makes sense to have a clean enviroment.
I dig a hole and put the eggs on the ground that way they don't explode or are expose to other animals.

In that case I'd just try and do the staggered hatch, give the eggs a chance to finish developing.
