I currently store my eggs in the fridge in polystrfoam egg cartons. I'm considering getting some ceramic egg trays (like the bottom half of an egg carton) as I like the idea that these can be washed, also will be sturdier. My only concern is this means the eggs would be stored uncovered. Is there any reason this would be a problem?Would the shells "dry out" or absorb odors? TIA for any comments on this.
