Is it possible to have humidity too high?

    I'm just wondering if its possible to have the humidity too high? We've been using this cabinet style incubator for months now and most of the time have great hatch rate but now with eggs coming in cold and temps all around colder the rates have gone down but still doing good!
    Anyways my main question is the incubator i dont know a lot about. IT has 2 thermometers on the side of it, one leads to the water wick thing that goes in the water for humidity and the other i assume is just the inside temp but both were set at same temp when i started using it and we have kept them at same temp. I've had to bump it up a little since the temp in teh house is colder now since its freezing outside cuz we had eggs hatching 2-3 days behind but otherwise all well. The one i wonder about is the one that leads into the water reservoir...what should that one read? It's not a percent its just a thermometer? I never adjust it and hatching still happens so it cant be all that bad but i wonder if i should?

    *feel free to email me privately in case i dont get back on here and i also have pictures of the incubator and the thermometers but i have to put them on a site to put them on here.

    Heather that is a wetbulb, check ou this site for more info on what it should read......I will e-mail ya too!


    do a "find on this page" for "Wet-Bulb" there is a table in there that tells you what the humidity is for that temp on the wicky thing

    Here's a link to GQF's specfic instructions for the wet bulb Thermometer/Hygrometer as used in a cabinet incubator.

    https://www.gqfmfg.com/pdf/3018 instructions.pdf

    Note especially this paragraph:
    Because the wick can become coated with impurities in the air and water, it is best to use the wick for about 24 hours only as the reading may seem higher than it is once the wick becomes soiled from deposits. If the hygrometer is reading 95°F or higher, it is most likely that the wick is not working and should be wetted or even changed. Wicks can sometimes be washed or the ends reversed on the probe to extend the life of the wick.

    You mentioned the change in weather as well, so I'll offer some advice on that since the hygrometer advice you've received is great.

    In the fall/winter months, frequent egg collection is critical if you're intention is to incubate. Personally, I go out hourly to ensure eggs don't get a chance to sit in the nest very long or a chance to freeze or get too cold. I have found if an egg gets too cold, the yolk stiffins. This can cause them not to develop or to develop but they may not be able to absorb the yolk completely during hatch. Just something else to consider.

    Not only is it possible for the humidity to be to high, when it is the chicks drown.
