compare the readings to a chart to translate from wet-bulb/dry-bulb reading to

"percentage humidity".

From the relative humidity table, you can see

60% humidity reads about 30.5 degrees C on a wet-bulb at 37.5degrees C.

60% humidity reads about 31.6degrees C on a wet-bulb

at 38.6degrees C. 80% humidity reads about 33.8degrees

C on a wet-bulb at 37.5degrees C.

80% humidity reads about 35degrees C on a wet-bulb at 38.6degrees C.

Getting your humidity to become as accurate as your temperature is nearly

impossible. It is almost completely impossible with a small incubator. Try to get

your humidity as close as you can, and you'll be fine. Just being aware that

humidity is important, and trying to get the numbers to come in close will be a

huge help to your hatch.

If you can hold within 10-15% things should turn out fine.

Temperature on the other hand, is CRITICAL!! !!! We hate to beat this point to

death, but a small deviation in temperature (even a couple degrees) can and will

ruin a hatch. Or, at least turn a potentially great hatch into a lousy one.

An important point about incubator humidity

As seasons change, so goes humidity. When you are incubating eggs in January

and February it will be very difficult to maintain a humidity that is as high as

you like. That's because the outside humidity is so low. (Depending on where

you live). By the same token, when you are incubating in June and July the

outside humidity is usually much greater and the humidity in your incubator

will most likely get much higher than you would like. Hatching problems will

change as the season progresses. If you are doing things the same way in July

as you were in January, you have to expect different results. All we are trying

to say here is that your incubator humidity changes directly according to the

outside humidity. Low outside, low in the incubator. High outside, high in the

incubator. To adjust for these problems, you need to change the surface area of

water in your incubator.

What is surface area?

Surface area is "the amount of surface of water exposed to air in your

incubator". The depth of water has absolutely no bearing on the humidity in the

incubator (unless the depth is zero). If the humidity is too low in your

incubator, add surface area. Place another pan of water in the incubator, or

some small, wet sponges. This will help. Alternatively you can spray the eggs

with a fine mist. To decrease the humidity, remove surface area. Use smaller

containers of water, or undo some of the things you've added.

How long will it take to incubate chicken eggs?

The incubation period for chicken eggs is 21 days. You should turn your eggs at

least three times a day for the first 18 days, and stop turning after the 18th day

(or use a hatcher if you have eggs from different days in the same machine). This

allows the chick time to orient itself inside the egg before piping.
