You only turn for first 18 days, in fact 14 days is all that is really necessary. Humidity depends on the ambient level in the room, so that depends on the location which must be in a stable area above 20C but with no direct sunlight. We don't put any water in until day 18 when turning stops, but we do check air sac development very carefully and adjust early humidity accordingly.

You are more likely to run into problems if you add too much water than if you add too little. If it's too humid, especially in the early stages, the chicks risk drowning because too much water vapour will penetrate their porous shells. Their shells are porous to let in the air they need to breath, and if it's too humid they can't get enough oxygen. Many people nowadays add no water at all, or very little. when i used a Brinsea Advance I incubated totally dry except for the last day or so before the chicks were due to hatch, but that was for quail eggs, which are even more sensitive to high humidity than hens' eggs. I would add just a tiny bit of water, less than one side of a reservoir, and see how it goes. The fan in the incubator will be drawing air in from the surroundings, and if you have a barometer or a weather station in your house it will tell you what the humidity is in your home. If its around 40-45% that's fine, no need for extra water. If it's higher humidity than that, then definitely no water! In our house ATM, our weather station says 43% humidity, which would be OK for incubation.
You can also buy a little hygrometer, which is about the size of an egg and sits inside the incubator and gives readings of what the humidity inside is like.
there are many types e.g. this one http://www.ebay.co.uk/itm/Mini-LCD-Digi ... eQuzLFXMRA
though this might not be suitable if it has a sensor on a cord that would interfere with the dome closing, best get a battery operated one that just sits inside the inci. Just search Hygrometer on eBay.

I found a humidity chart on-line somewhere, which compared humidity to temperature for a given amount of moisture in the air. So an ambient temperature of 20C with 75% humidity (we live in an old stone house) becomes 37.5C in the incubator and 35% humidity if I remember correctly. We still ran dry up to day 18 then filled just one reservoir- two would be necessary for a very dry environment. Lots of incubators are made in Italy or Spain where the air is very dry and two reservoirs are necessary, one for incubation and then two for hatching. As Marigold says, you stand far more chance of success running with lower humidity than higher in the first 18 days. Also consider that the figures quoted by everyone are based on an average shell porosity which was derived by someone decades ago. Our Wyandottes laid eggs so sound that even running dry the air sac wouldn't develop properly and we lost one of 12 at hatching.
