Refrigeration doesn't seem to harm eggs- in my experience I think the refrigerated eggs can be held longer before being incubated.
The biggest harm to them is major temperature change. Take refrigerated eggs out and leave warm to room temp slowly, I usually take them out 8 to 12 hours ahead of placing in incubator.
