We have a huge family vacation coming up in four weeks. Lots of big breakfast eaters. I'd like to provide all the eggs so no one has to buy eggs and its a cool thing I can contribute to the gang. If I start saving them now, they will be four weeks old when we begin the vacation. Do you/ would you consider four week old eggs from your backyard flock still "fresh" or at least "fresher" than what we would buy the night before at the grocery?
