I am having problems with my Brinsea Oct 20 (not the advance) . I know this has probably been discussed several times but I am in lockdown right now and need some help. Day 18 was fine for most of the day then the humidity started dropping I have a little sponge under the vent where I am adding water with a straw but I am constantly having to monitor it . When I got up at 3 am the humidity was down to 49% I am hoping that didnt ruin the eggs . So any thoughts or idea would be greatly appreciate . I have more eggs to go into lock down next week keeping my finfers crossed for this one . Also I have to hydrometers in there both are running percentages off from each other I dont know which one to trust :( .Can someone please recommend a good one that they have used and works well .

As for hydrometers, I use two different ones that are great - both are digital combo temp/humidity gauges. One is by Accurite and the other is by Vicks. The Accurite one can be picked up at Walmart, and the Vicks one I ordered from Amazon here.

I did try the paper towel before I put the eggs in and the humidity kept spiking really high maybe I was doing it wrong ? Can exactly how you do it and how much water you put in the channels .I dont have any pips yet that I can see .And thanks for the info on the meters I will go and get them today .
Also make sure your vent hole is open all the way to allow oxygen in to the hatching chicks, and it also helps to regulate the humidity when done this way. Once my eggs start pipping my humidity usually goes to about 60 to 70 percent and stays there, which is perfect.

It sounds as if your reservoir may be running dry which allows your paper towel to dry out. Can you fill it with your straw?
If you spill water when filling the reservoir you get things wet you don’t intend to. That gives you a larger surface area so you get a humidity spike until it dries up. Is that what you are seeing? If that’s the case you need more reservoirs or more towels.
I don’t think this is it but a few years back during incubation I hate a mysterious drop in humidity. When I added water I did not get the lid back on perfectly, it was cracked. The heater was able to keep up so the temperature was fine, but the humidity was noticeably lower. You might look for something like that but I think something is drying out.
No problem! I fill both channels with water but only do the paper towel in one. I use two paper towel sheets folded together. For my humidity I just shoot for 60% - 70%. When the chicks start pipping it raises the humidity also.
As Ridgerunner said you might also want to calibrate your hygrometers to make sure they are reading correctly
