I've got all colors too :) 3 gold, 3 blue, 2 silver and 4 bronze. Didn't want to get egglocked with so much appearing in the abandoned pile, and don't find it fair to collect full house if others are still unable to catch any. I also bred 1 gold and 2 silver eggs from the caveborns I have, but that was to pass them to a friend.
I got a male and female pair for each of the 3 biomes, for all 4 colours :P (So I've got breeding covered!) And I ended up getting a few extra, though I've also given quite a few away particularly during the Bronze drop as that was a tough one for people with slow connections.
Is your forum username the same as the one here? I'll PM you a teleport link for some CB silver eggs when I get out of scroll lock tomorrow :) (Otherwise we can meet on The Elder Scrolls wiki chat- yeaaaah I saw you on there! XD)
