    I've recently bought a janoel-10 incubator as my trusty broody muscovy passed away a couple of months ago. I've got it set up with a hygrometer and additional thermometer and it's reading 45% humidity and 37.8°c and keeping steady. 6 khaki campbell eggs are arriving in the post tomorrow so fingers crossed they make it here ok.

    Just a question about weight loss as I'm a little worried about humidity. I know they have to lose 12-14% of the original mass but is it consistent throughout incubation? Or do they lose more towards the end, for example? Just trying to get some planning in place...

    On paper I've got 45% humidity until day 25, then raised to 65% at lockdown, then raise again to 75% when the first duckling pips.
