Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
It would appear you gave me the wrong egg; this one has a shiny value of 2307. Here's a screenshot of the one you sent: http://i.imgur.com/UMm2FM1.png I'll go ahead and give you this one back and give you a chance to find the correct egg. :)
I actually had a friend check it for me (Hozu here on Smogon) as I don't have access to instacheck. I'm sure he'd be glad to check the eggs for you if you'd like to message him prior to our trade.
