Hello! My first hatch with the Brinsea Octagon 20 Advance EX was chicks, and I had a great hatch rate. However, for my second hatch I plan to try and hatch ducklings. I'm still very new to this, and could use any advice people have as to how I should use this incubator specifically for ducks! I'm a teacher and will be hatching them in class (they have a great home set up with a child's grandparents) so I'd really like to have a successful hatch or there will be a lot of disappointed children! I was hoping to get the eggs around February, but is that too early for duck eggs? Also, should I hand turn for duck eggs vs letting the incubator turn them in the cradle? I'd appreciate any help or suggestions--I'm completely new to ducklings!
