READY? MoreEggs..Incubator

[1234duck]

Should I get rid of eggs in Incubator? It's been 7 days, can't see anything but yolk. I think they were duds or I messed them up from day 1/two weeks ago. ~Now NEW Eggs **I have (7) Chicken eggs & (13) Duck eggs. Fresh from outside, this evening. Eggs are @ room temp. *I put X on 1 side... 0 on the other side. *Incubator is Ready.. >>>}DO I WIPE OFF/CLEAN THE EGGS?{<<< ANYTHING I NEED TO DO BEFORE I SET EGGS?

Thanks, Julie
