You seem to know all about incubating----I have done a far amount of it in the last 30 years but I Like to Learn new things. I am trying to figure out the purpose of using "Rice, rock salt and silicone dry-packs" to absorb some of the moisture instead of just removing some of the water you put in it------to increase the moisture?? Help me understand the benefit of doing that. ThanksYeah. Even so, never seen that kind of spike in a forced-air bator! Thank goodness I caught it in time, I've had to keep it at 25-30% to try and trigger air cell evaporation before hatch. For the first two weeks the air cell didn't change one millimeter. I'll replace the water just before lockdown.
