Can you change humidity goals throughout a hatch

    Hi there,
    This is my first hatch and I have been keeping humidity between 45-55 (probably closer to 50-55). I am only on day 3 and after more research think I should have it closer to 40-45. Is it ok to just reduce it or because I’ve started higher I should continue higher for the whole first 18 days?

    50-55 is what aim for for the first 18 days. It works fine for me.

  3. You won't go wrong at 65% especially the last 3 or 4 days. Personally I like 80 to 85 %

    In small incubators, those that only hold a few 1000 eggs or less, humidity is a moving target because you can't control it that precisely The outside humidity will dictate the humidity in your incubator more than you can manage it yourself. Just remember that humidity is a moving target, or something to shoot at or for. Don't go running around opening and closing off the fresh air vents willy nilly or you may smother your chicks in the cradle.
