So, we just hatched 9 of 10 duck eggs using a broody hen and decided we were hooked and wanted to try again though we felt Ms. Hen needed a rest! My husband built an "incubator" but after reading all these posts about PC fans and wiring, etc... I am wondering if it really needs to be that complex or will ours work? He made a wooden box and attached wire for the eggs to sit on. He had made a top out of plexiglass with wooden sides but we had trouble getting the temperature up through the top so we just took it off. They are under one heat lamp and we're keeping the temp. at 98. With a humidifier and a cookie sheet of water under the eggs, the hygrometer measures 50% humidity. What are your thoughts? Thanks!!
