So I am going to go ahead and be my normal opinionated self and do some disagreeing.
Yes, I agree condensation is too much humidity and needs to be cut back slightly. BUT if you are going to be "red" and open the bator I would caution against going too low. I have the LG (9200). I have great hatches in it. Mine does have the fan, but I am a meddler. I am full on red at hatch. At day 18 I up my humidity to 75%. At hatch once they start it often goes up to 80-90% No problems. Now, because I do open my bator during hatch it doesn't stay up at 85% or more that long and I do not get condensation build up either. I also remove my chicks as they become active, so that in itself removes some of the "extra moisture".
Here's where I say, I have never lost a pipper/zipper. My last hatch was 100% from lockdown to hatch. I highly believe it is better to run high than low (as long as there is no condensation build up). I personally do not like seeing my bator get to 65%, that is when I start wetting my sponge to get it back to the 75% so that the next time that I open I know I have adequate humidity. My disclaimer: many people hatch at 65%. The majority of those are hands off hatchers to my observations. There are always those that have opposite experiences as well and will always argue their way is the way. My philosophy is, if it works for you, it doesn't matter what anyone else is doing. I actively disagree with a lot of the common ideals of hatching, but I also validate that different things do work for different people.
I was going to send you to her site...lol
The LG 9300 is notorious for the display (both temps and humidity) being off.
I appreciate you speaking up. I had read so many different things that I really wasn't sure where temps and humidity should be at for hatching. Unfortunately I didn't read enough about the LG9300 before I bought one
