I apologize in advance for bringing this up again since there are hundreds of posts about this on the Internet. The problem is that I feel like I'm going in circles reading them. I see recommendations that range anywhere from 30% to 70% humidity before lockdown, and most of the people who give opinions on proper humidity say they have vast experience with hatching Call ducks. They all sound like they really know what they're talking about, so I don't know whom to believe since this will be my first time using artificial incubation. (Beginning tomorrow, so I'm getting kind of anxious from feeling like I still don't know the correct answer.) The incubator I'll be using is a Brinsea Octagon 20 Advance EX. The eggs I'll be putting in tomorrow were ordered from an eBay seller as a kind of trial run to make sure we know what to do when our show and show breeder ducks start laying next year. If I have a low hatch rate or none at all from these eggs, I want to be able to feel sure it wasn't caused by me doing something wrong with the incubation. Thanks so much to anyone who can help!
