For powedered cures. I wipe the blood off powder them up and then toss in the fridge for 4 to um when I remember to pull out of the fridge. If the eggs are lucky i may flip em once in a while. Ussually after a week, into the freezer they go. I always like freezing my eggs before there first use so that they are milked out after the 4th or 5th cast.
