As my girls are almost at POL, I've been reading up on washing/refridgeration/etc. We've decided to not wash our eggs but keep them cold (mostly because we're very short on counter space, but are OK on fridge space.) In all the articles I've read, they end up saying "wash the bloom just before you use the egg." Is that part necessary? Can't I just keep the bloom, crack the egg, and away we go? Or is there some contamination risk this way?
