I hope you don't take this personally, but this is a classic case of putting the cart before the horse. How in the world you got to having eggs without the knowledge not to mist them is perplexing. If you put enough water in the vermiculite (or whatever your using) and seal the lid well enough you shouldn't need to be adding any water at all during the incubation. My guess is you have multiple problems going on with your incubation technique. Long story short you need to get on these forums and you tube and put in the hours researching. As for the eggs you have going right now, my recommendation is to cut them. Even if you cut eggs a week early they will be fine. just cut a hole or flap in the top and then put them right back in the incubator. My guess is your temps were low and obviously your humidity was fluctuating, which stunted the growth creating longer incubation time. I incubate at 89 degrees with 99% humidity in my tubs (dry eggs) and they hatch on day 55.
