I have the hova-bator incubator with the fan and my temp is great, but the humidity keeps dropping down to about 40% and then I had water it goes to 45 - 50% and within a couple of hours it drops again. This is only the second day so I have no idea if I am doing this right. I have been reading all the great threads on here about incubating and hatching. Also is there a way to check if your eggs are fertile before you put them in there? I don't mean the eggs you are going to incubate but your chicken eggs in general. Thanks for answering all these dumb questions from a newbie.
