Quote:Are you only filling the one-cup well that's in the middle? If so, and your humidity is more than 55%, you need to get/cut/make some flat pieces of styrofoam like what's found on restaurant carryout boxes. Cut various size pieces that slightly smaller than the sides so that they will float freely, thus covering the water. Doing that will decrease the surface area of your water, hence lowering the humidity. I have two Hova-Bator Genesis 1588's and they have never reached 81% with only having water in the main center well, i.e., I think you're either filling more than one well, or water is overflowing into a second well, thus increasing the water surface.
What day are you on? Im on day 19 with some silkie eggs and the humidity is 80%, in my 1588 forced air. Ive been keeping the humidity higher in my forced air.
if you dont have eggs in it at the mo you have several options. if you have water in takeit all out and see what the humidity is, if its still too high then you have a choice. place a SMALL saucer of table salt in the bottom of the bator DO NOT put eggs on the salt, salt will absorb water vapour and lower the humidity but can be fiddly as you dry out the air too much in wich case you then need to add a small wet sponge or whatever to the incubator to raise the humidity, i always keep thos little packets of desecant that come with some electrical equipment and i use those instead of salt. but i am sure others will have ideas for you as well
Taking the red plug out of the vent hole on top will help lower the humidity a bit. I agree with Joe, though. I think you have water in too many of the water wells. With the red plug out and only the center well filled, my humidity stays in the low 40's. With the two center wells filled and the red plug in, I get around 65%. It will be different with different ones of us, but 81% seems real high. Calibrating your hygrometer is also a great idea. Those things can be way off. Until you calibrate it, you really don't know what you have. Calibrate hygrometer https://www.backyardchickens.com/forum/viewtopic.php?id=115856 Good luck!
