I have read mixed reviews on refrigerating vs room temp. Putting in refrigerator definitely buys me more time, but I wouldn't want to do it if it will reduce my chances at setting/hatching time. Decisions, decisions, decisions!I store mine in an egg carton in the fridge and have hatched eggs that were four weeks old with great success. Store at room temp, after 7 days the chances of hatching go down drastically.
