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.
