    I'm new too and have been going off of the sticky placed at the top of this forum. Here are the pertinent links.

    "Read Me's on Hatching"
    Incubation and Hatching (including troubleshooting links): publications/b6092.pdf … Incubators … emperature

    Humidity discussion:

    actually copy just the stuff on humidity and temps so I wouldn't have to keep going back:
    "Humidity is carefully controlled to prevent unnecessary loss of egg moisture. The relative humidity in the incubator between setting and three days prior to hatching should remain at 58-60% or 84-86 degree F., wet-bulb. When hatching, the humidity is increased to 65% relative humidity or more.
    Temperature, humidity and ventilation of
    incubator (set stage)—Temperature in the
    incubator should be 99.5 degrees F to 100
    degrees F (37.5 degrees C). If the temperature
    deviates more than 1/2 degree from 100
    degrees F, a poor hatch is likely. Temperature
    should be checked at least twice a day.
    Relative humidity should be set at 86
    degrees F to 88 degrees F (30 degrees C) wet
    bulb temperature. Humidity should not
    fluctuate more than 1 wet bulb degree. If the
    incubator uses a passive humidity control
    system, water should be added daily to the
    water pan or trough to ensure correct humidity

    Humidity in the incubator varies with the different makes and models of the incubator. Read
    your manual for the specific setup for your incubator. Most incubators recommend 58-60% or
    84-86 degrees between setting the eggs and 3 days prior to hatching. Then you would increase
    to 65% during the hatching process.
    The embryo must have the proper amount of heat and humidity at all times. Incubator temperatures
    not only regulate and determine time of hatch, but also plays a very important part in the quality
    of the chick you will produce. Humidity should be carefully controlled to prevent unnecessary
    loss of egg moisture. Ive added a picture to show the normal size of the air cell, which is located
    in the large end of the egg, after the 7th, 14th and 18th day of incubation. You can check this
    by candling the hatching eggs. There is a product called a candler that you can purchase to
    correctly candle your hatching eggs. Also, always remember to keep the water trays in the
    incubator full. This plays the most important part of your humidity."

    The other low humidity levels you are hearing about are for the dry incubation method. You can do a search on it to get the specifications. I'm doing the old fashioned way because it's my first hatch. Although I will use an egg carton for the actual hatch.

    It can be confusing. Good luck in your search and hatch. [​IMG]

    Im sure they will be fine. I would lower the humidity and keep pressing on. Candle them on day 14. I am by no means an expert, but from my last experience, less humidity the better. My first hatch I had babies basically drown due to humidity issues. Read on here under the learning center,...they have some good info on hatching,..including dry hatching. Good luck! [​IMG]

    I have been doing lots of research on this and it really just is opintion that varies from person to person. I decided to keep mine around 40% 1-17, and 65% 18-21, but this is my first hatch. We'll see.
