I've got a big metal Brower that I found through a friend. It's a still air incubator, so I'm thinking of using it for duck eggs. I've got duck eggs started in my Marsh Roll-X, but don't have duck grids, and it's really tough to keep the humidity up where it belongs. Any thoughts about whether I can move these eggs? Any info on using the Brower, such as how to add humidity? I'm thinking a bowl of water and a sponge? Any tips appreciated. I've got two Pekins laying, and would like to hatch a bunch of yellow fluff balls this year.
