Balut is a duck egg with a nearly developed embryo inside, commonly sold as street food in the Philippines. You can try it at Maharlika (351 E 12th St / btw 2nd Ave & 1st Ave). If you have the courage to try balut, order it as soon as you walk in, as it might take a while to prepare. Plus, don't forget to try the sisig (pig snout, ears, belly with egg).

2. 1000-year-old egg
In Chinese cuisine, these are duck or chicken eggs that preserved for at least 100 days in a clay-like mixture of red earth, garden lime, salt, wood ash, and tea and wrapped in rice husks. In the process, the egg yolk becomes dark green or gray and assumes a sulfuric smell, while the white turns into brown jelly.
You can try a century egg with lean pork or with jellyfish at XO Kitchen (148 Hester St btw Bowery & Elizabeth St).

3. Eggs of Unusual Birds
Whole Foods in Lower East Side (95 E Houston St) and Tribeca (270 Greenwich St) carry ostrich, pheasant, duck and quail eggs. Ostrich eggs are the largest of all eggs, measuring on average 5.9 in long, 5.1 in wide, and weigh 3.1 lb. I also randomly stumbled upon ostrich eggs at a farmer's market on Upper West Side ($30).
Eating ostrich eggs can give you a stomachache if they are not cooked properly. If attempting to boil, it will take 90 minutes and the outside will turn to tough rubbery consistency. Our recommendation is to make a giant scrambled egg party out of it and save the shell for decoration!

4. Scotch Egg
A Scotch Egg consists of a hard-boiled egg, encased in sausage, coated in breadcrumbs and deep fried. It is commonly served cold, with a pickle. You can try it at The Breslin (16 West 29th Street), $8. Be sure to also order the Breslin's gigantic stuffed pig's foot for 2 (beware that our group of 8 couldn't finish it!) Other notables on their menu are rabbit, chicken liver and headcheese terrines.
5. Hakone's Owakudani Black Egg
I tried these on my recent trip to Hakone, Japan. These are simply eggs boiled in sulfur spring water in Hakone, a town filled with onsen (hot spring resorts). These eggs look cool but they taste like regular boiled eggs.
We had some other interesting things in Japan, including bizarre items in a conveyor belt sushi place.
6. Twin Eggs
Closer to home, you can sometimes find eggs with two yolks in your regular supermarket. We were so lucky, we got 2 twin eggs in the same dozen! Make sure to pick up the non-organic, stuffed-with-hormones type to increase your chances.
