Borrow a trailer or take yours and make the trip. I agree with the above poster, the feed shop is making the poor choice, no need to support them unless you have to.
And albumen is mostly water, actually. But I know what you are getting at, and if I were adding the egg yoldk for the macronutrients(fat, protein, carbs), I would include the albumen and cook it. But since I am not adding it for the fats and proteins, I do not. Cooking destroys a lot of vitamins, denatures proteins(inactivates enzymes, destroys antibodies).
