you should be o.k. with the eggs, I have a hen that will get off her nest to let the other hens lay egg's in it, she will get off the nest for quite a while and the eggs are exposed to a average of 45 degrees most of the day. I have allot of nesting material to contain the heat. If you have them in the incubator the heat will be insulated and the temp should have only dropped a fer degrees. Water is a GEO thermal insulator. I never give up on the eggs until the time is up for the eggs to be on hatch day. Although I don't get as many fresh egg's every day because smarty pants cant lay on enough eggs. she looks like Fog horn leg horn.
