My humidity goes up that high anyway and always causes problems since i dont hatch ducks. Ive lost quite a few hatching chickens to drowning while trying to get my humidity down because its always so humid here anyway. The average humidity in my house during hatching season is 65% plus in an enclosed incubator, causes big headaches when I hatch. last time I had 56 eggs go into LD and only 22 hatched, even though almost all of them pipped, some even made it to partial zip before and I just couldnt keep it low enough for them. Next season i will have to invest in a dehumidifier.how do you get your humity that high? i have ancona duck egg's due for lockdown on june the 3rd and i'm having a hard time just keeping the humdity at 50%
