    OK I know that at day 18 the humidity should be raised up to 70% but what is an acceptable range at this time? Would it be 70% to 75%?
    Just wondering this because I am not 100% sure if I can get the humdity at exactly 70%...or even near it, 1 or 2% away. I can get it above 70% im sure but under not sure.

    I usually get mine to around 60-65%. As long as your close don't sweat it.

    I too keep mine at 60-65%, because once they start hatching the humidity goes crazy and ends up closer to 80%.

    Just as long as you have it in those ranges it's fine. When your chicks start hatching the humidity raises anyway, don't sweat it. See how well the chicks come out of the shells (meaning a clean hatch) not messy and that will let you know for next time to either increase or decrease your humidity levels for your climate and house. I have clean hatches using 40 to 50% first 18 days and 60 to 70% the last three.
