Question, which is more important, humidity or temp when storing hatching eggs? The only room with a humidifier is kept at 70degrees for the incubator. The rest of the house is low to mid 60's, but dry as we in Northern Indiana. Thanks!Yup. Eggs can be stored (large end up) for up to 2 weeks at room temp (but I think 50 degrees in a place with high humidity is best) before fertility levels start to drop.
