Found 47 duck eggs on Friday. Hens had a hidden nest. Put them in my bator Friday night... How do I keep the hummidity right when I can't fit a bowl in to raise it? What is the best hummidity for duck eggs? This is my first time incubating duck eggs from the start, so I need a little help please. I bought a book but kids did something with it and now I can't use as a reference, ARGHHHH! PLEASE!!
