I'm on day3 of incubating duck eggs & had calibrated my new hygrometer in a bag with wet salt in a bowl & it was spot on. But when I couldn't get it above 35% I knew something was up so I got a little regular hygrometer(not digital) it said it was around 60%-65%! I had calabrated that one in the same way & it was spot on too. So I took out the jar of water w/sponge and calibrated the digital probe one again but this time with only the probe in the bag & its like 30% off! So now that I have a working hygrometer should I drop my humidity since I'm only on day 3 and if I drop it how much and how fast? Please help!!!!
