How shall I arrange my slowly-eating plan and preserve a box of 5Lb frozen eggs over a long period? I have a box of 5Lb of frozen eggs with citric acid, where 


  1 Lb is 9 large eggs
  
  Unopened product should be used within 3 days of thrawing.
  
  Unused portion should be kept refrigerated and used within 24 hours of
  opening


I can't eat all after thrawing and opening it. I can only eat 1 egg i.e. 3 table spoon per day. How shall I arrange my slowly-eating plan and store the remaining  frozen eggs over a long period?
I would thaw one pound, and make something with it that I can freeze. For example. I bake quiches in leek and chard season - each quiche uses three eggs. They freeze beautifully once cooked (I slice them into servings before I freeze them) and it's easy to remove one slice, warm it in the microwave, and enjoy. So make three quiches and freeze them, you could eat two slices a day if you wanted to.

You could experiment with a variety of egg dishes that are not just "one egg, scrambled", or "one egg, fried" to use 9 eggs at a time. The internet is full of recipes for frittatas, quiches, soufflees, egg casseroles, and the like. Just remember to cook your creations before freezing, and to partition them for serving.
