Clean the inside of the incubator with soap and water, and let it dry completely before putting it away. These times may vary slightly, depending upon incubation temperature, genetic differences, and other factors. The success rate in hatching eggs is quite variable. Chickens and some upland game bird species are much easier to hatch than are many waterfowl species. Even commercial hatcheries having specialized equipment may not have more than an 80 percent success ratio.
Goose eggs can be particularly difficult to hatch.
So don't be disappointed if your hatch is not highly successful. Get as high-quality supply of hatching eggs as possible, provide an incubator that can provide a good environment, and then pay close attention to the operating procedures. Recommendations for chicken eggs generally apply to hatching eggs of other species. However, waterfowl require greater humidity. Increase the incubator humidity by using a larger water pan.
