Personally, if you wanted to set them, I would wash them with
Brinsea's egg wash/incubator disinfectant. I just hatched a batch of eggs and got over 60 to hatch, I was really happy, they were popping out like popcorn.
I wanted to experiment and see. I was all stressed out about some goose eggs I got from
ebay that came smeared with feces bigtime. So, as an experiment, I washed all of the quail eggs in the
Brinsea solution. I followed their directions exactly except that I lowered the water temp 5 degrees to 105 (
Brinsea say to use 110 degree water) -- I did this because I was concerned that quail eggs, being so small, might be more likely to be damaged be the hot water faster than a larger egg with more thermal mass.
Egg washing is so controversial. I just wanted to see if it would help, hurt, or whatever. I think it certainly didn't hurt, and may have helped. I know that I won't be afraid to wash and set soiled eggs after this experience.
