Ok, I thought I had covered everything, but my friend Kimberly has asked a bunch more questions that I'm sure others are asking too.
Do I wash the eggs? Yes. I know some people feel you should leave the 'bloom' on the eggs and have all sorts of claims as to why this is a good idea. But our chickens lay their eggs where ever they like and the eggs come from the barn with all sorts of 'stuff' on them. I give them a quick wash under running water in order to cut down the chances of spreading e.coli. around. That and I think it's disgusting to crack an egg into a recipe that's covered in poop.
How long to keep fresh eggs? Are you ready for this -an unbelievably long time, so long that we've never had a bad egg. You may not believe this, but store bought eggs can be about a year old!! Yep, you read that right, a year. I forget which show I saw that on, but it was one of those 'investigative news-type' shows that you can trust. My MIL stores her eggs in the basement (when she gets backed up), it's cool and they keep for months (if needed). Remember, in Europe people don't even refrigerate their eggs, fresh eggs are kept on the counter. Fresh eggs are in such demand that MIL's eggs are usually never more than a week old, sales slow a little during the bad weather months.
Blood spot in 'organic' store eggs? I'm not sure whether you can salvage those. You still don't know how old the eggs are or whether there was a rooster involved. If the eggs aren't yours (or a friends) I would be tempted to toss the blood spots. I'm much more cavalier with egg safety (eg., eating dough, meringue) but that's because I know how old the eggs are and the conditions they were harvested under. I'd be more wary with store bought.
