I just started my first batch of eggs of large and bantam eggs (I talked to some people who said they had done it and were successful) last Thursday on the 21st. I have the temp at 100 and the channels at the bottom full. The person before me who had this incubator hadn't used it in years, but they told me to just fill the channels at the bottom and I'd be fine (that's what they did and had many successful batches). But I got worried, so I bought a hydrometer and stuck it in there. It read 38-39. I messed with the hydrometer a lot so I didn't think that was was correct, so I bought another one. It read the same thing! So I added a paper towel (because I know the temp is suppose to be between 40-65) and then the humidity dropped to 34-35. I'm so lost and need advice. My incubator is almost exactly like a Little Giant but seems to be an off-brand to it. Also, if it matters, the humidity where I live is 45-50.
How long does it take the humidity to come back up after I open the incubator?
