I have been thinking about blowing eggs for weeks now and just gave up and bought already blown ones on eBay here. Lazy? Perhaps. However, I get the heebs when I think about blowing eggs so I bought 15 eggs for $10 shipped. It was worth it for me to not blow eggs.
The seller was super nice and you can buy more than chicken eggs on eBay - quail, rooster, duck, ostrich... OK - not rooster. Just seeing if anyone reads this.
