where its placed in the house will matter...it's my experience that anywhere from 25 to 40% for incubation then up to 65-70% for hatching
nearing the last week avoid letting the humidity dip below 35-40%....my last hatch the humidity dipped to 10% the day of lock down (day 18) I pumped it up and for the most part everything was okay but there were a few that obviously dried just enough that when the humidity went back up the inner membrane turned to glue....if I didn't know what was happening when they were trying to hatch it would have been fatal for them...
what day are your eggs? if you can get your humidity down to 45%...the biggest issue is making certain they dehydrate enough for them to have a big enough air cell at hatch time...I hardly ever add water until the last few days because the humidity is usually good here if there are quite a few eggs in the incubator...
you just have to figure out what's good in your environment ...maybe remove all the water put the eggs back in and watch the humidity for a while if it doesn't get high enough then add a tbsp. at a time waiting an hour or so before deciding you need more...I have a few of the incubators with the hydrometer in the lid...the temp and humidity are quite different near the eggs
Hope I haven't confused you!!
Yes, thank you!! this is basically what I'm doing now.. I ran my bator for a whole week leading up it to make sure everything was good, and it was! It seems like adding the eggs threw off the humidity. I'm not sure if that is a real possibility but it seemed to happen at the same time..
Now, all the water is removed from the chambers and I sprinkled a little rice in the bottom to help absorb moisture.. here's a pic:
I'm leaving for the next 4-5 hours so I will check the humidity when I get back and let you know!!
I also have 2 eggs which sweated a little bit. They were detached air cells when i received them and today is day "3" (or 2.5) and they don't look like they are developing at all when I candle... could the 2 sweating eggs have boosted humidity that much? I WAS very careful to raise the egg temperature slowly, I am not sure if I caused the eggs to sweat, or if they were already too porous (the problem eggs were from 1 shipment that had mostly detached cells...)
