Can't wait to try the heart shaped eggs! I've never heard of that before! In addition to freezing the extra eggs (the whisking method, in large ice cube trays), my husband also experimented with dehyrading the eggs this winter. We have a large food dehydrator, and he lightly beat the eggs in a bowl, then poured them onto the plastic mat you use to make fruit rollups. The end result is not very pretty, since the eggs basically turn into a powder, but they work really well for backpacking/camping. You just add water. He said it reminds him of his army days..... We dehydrated a bunch, vacuum sealed them, and put them in our "earthquake cubby" of emergency food supplies.
