Both schools of thought are equally represented on this site and on several other chicken-keeping sites. Both sides claim "scientific" basis for their belief. So what's the factual answer? I know that it's not necessary to wash the eggs, but if I had to for some reason, is it safest to use COOL or WARM water? Any claims provided or stated by your local government cooperative extension board or by your local veterinarian, or by some lab or ??????????? Don't want answers based on folklore and/or personal experience. Thanks!
