temp and humidity varies depending on what type of bird your hatching.
for chickens, quail, and turkeys:
temps - still air 101, forced air 99.5 dont worry if the temp drops just a little, but try to keep it below 102. - hens cant keep it perfect either.
humidity - through incubation period 35%-50%, if you can let it run at 50% and dry out for a couple of hours. replace water as needed. open your incubator 15 minutes a day, the fresh air does them good.
during your hatch period (last 3 days) raise the humidity to 45%-60%. if you have to open your incubator to replenish the water, mist the eggs lightly with warm (close to 99 degrees f) water.
turn a minimum of 3 times a day.
use cartons to hold eggs upright if shipped. big end up- this helps aid in correcting displaced air cells.
incubation times
chickens:
standard fowl 21 days
bantams 18-19 days up to 21 days
turkeys typically 28 days
quail varies - pharoah quail 18 days - bobwhite quail 23 days
