First time using an incubator and just want to make sure I have it right

[Backwoodsnanny]

I have an LG 9200 that has been used for 2 hatches ( my grown sons) It does not have a turner or a fan
I want to try the dry incubation method and have read all posts related to that. I have also gone to the Cheat Sheet and read that but am a bit more confused now than I was to start.

The incubator instruction says to fill the bottom troughs with water from the beginning but the dry method says no.
I have read temp on top of eggs should be 102 but then have read everything from 98 to 101 for a start in a still air Incubator.

Also it says 30% humidity to start but what if humidity is too high in the room where the incubator is located?
I do understand that when I go to lock down I have to increase humidity to 65 -75% not sure which number to use.

I am assuming that the temp drop that will happen as I turn eggs wont affect them too much if I do it quickly and have also read movin g them within the incubator will help if all areas of the bator are not the same temp and that they should stay acclimated all in the same direction so chick will know which end is air sack end. What happens when chicks start to hatch and roll their brothers around in there? Does this hurt hatch rate?

Sorry for so many questions but would like to have a successful hatch which will mostly be polish chicks
One more thing when chicks hatch (if they do) and you leave them in the bator do you take them out on 3rd day even if some eggs still havnt hatched?I am asking this as by then there will be 3 day old egg shells in the bator. a hazard for bacteria growth I would think.
Any help will be appreciated I should be setting eggs by Friday if I can get questions answered all the information available here has me a little dizzy but am so thankful I found this site.

Oh as a side note I have two silky broody hens sitting on 19 of their own eggs who are on day 12 so should have fuzzy butts soon

I use the dry hatch method on very fresh eggs and add moisture for eggs over 5 days old as the air bubble in the egg grows and is needed for the developing chick. At lock down I use 80 % humidity and at hatch I remove the chicks and shells after each four or five hatch.
Last month we put an x on 12 of 24 eggs in an auto turner and rotated each x'ed egg clockwise a third of a turn three times a day the other twelve were just turned automatically. on hatch day the x's all hatched together right on time. The others pipped 5 hours to 12 hours later and two had to be helped out.
Anyway my thought is now; handling the eggs helps more than it hurts There are many opinions on your questions but I hope I didn"t add to to them.

I added a 12 v computer fan to mine and it made the temps much more consistent.
