Where are you located? what is your room humidity? I don't add any water to my bator during incubation and I leave the plugs out the whole time, but I have a styrofoam incubator and live in the midwest.Back from vacation and the incubator did not dry out as I thought it might. We are on day 9 now so rapidly approaching hatch day. I am still only able to get the hygrometer reading up to 44-45% and that is with both the plugs closed. I will open it when hatch date is closer but I worry about the humidity being sooo low. I added extra little cups of water and have it as full as it can get. Does anyone have more ideas for raising humidity level or should I just not worry about it?
My incubator is also in my basement by the sump pump, the room has about 60% RH
