I started incubating my first batch of large eggs and bantam eggs (I have heard from that it is OK from some who have done it) last Thursday the 21st. I have the temp set at about 100. I filled the channels at the bottom all completely full and started the batch. When I started, I didn't have a hydrometer. I finally bought one a few days ago and I thought it was wrong because it was reading around 38-39, so I bought another one but it was reading the same thing! So I added a wet paper towel, but then the humidity dropped to 35. I'm so lost and need some advice. I have an older incubator. It's set up almost exactly like a Little Giant incubator but I'm pretty sure it's an off-brand. Also, the humidity where I live runs around 45-50. I don't know if that matters.
How long does the humidity take to catch back up after I open the incubator?
