We just started getting eggs (2/day for 3 days now). I've just been putting them straight in an egg carton. But my husband is freaking out that I haven't washed the eggs - with soap and water. He's insistent that the eggs are crawling with bacteria and e.coli and it's disgusting because the eggs come from the chicken's butt. He says that it's the eggshell where the e.coli is because that is the part that was in contact with the butt/interior of the chicken. Please help me.
