i keep losing humidity

[Danbrobins27]

hello i am really having a stressful time with my duck eggs i have a 48 egg incubator Chinese one i believe and the duck eggs are on there last few days and i believe the humidity should be around 70% to 80% but i can get it to late 70's then it drops quickly over a period of about 2 to 3 hours down to late 60's i know im not supposed to open the incubator at this stage but i have been to try and replace lost moisture can anyone help as i don't want to lose these ducks so any ideas that will help raise and keep humidity would be great fully appreciated

Hi I had trouble maintaining my humidity I put some rocks in the water bit and put a face flannel that was wet with warm water in with the eggs but not touching any of them. I got my humidity up to 78 and at one point it hit 80 theses things worked for me don't know if they are right but I was prepared to try anything oh n the water I put in the water bit was warm water
