Coddle your eggs, whether store bought or from your flock. I was taught that over and over in chef school. Whether it is for mayo, caesar's salad dressing. Coddle you say. what's that mean : place eggs that are at room temp into a pot of boiling water with a slotted spoon or spider basket. Let them simmer in the boiling water 45 seconds. Remove with slotted spoon or a spider basket and use in your recipe.
Safety first, don't want to be known as the person that made your family or friends sick. In warmer weather do not leave items made with homemade mayo out in hot weather ESPECIALLY direct sun for more than 2 hours. So from fridge to table and back into a cold fridge, served in a shaded area, no more than 2 hours. When I worked in this Sicilian place they did a lot of specialty items for their deli case and made them with their store made mayo. BUT if they did a catering gig it was commercial mayo (pasteurized) only and the boss was really very specific about things being refrigerated in transit AND after 2 hours it was 86'ed.
BE SAFE, NOT SORRY...
