I have seen white duck and goose eggs and was tempted to buy some to dye. In the end, I didn't think I was going to have time -- and the article says they don't take dye well, anyway. I wonder why that is?
We didn't have white eggs where I was in the US either -- well, there were some, but weren't that easy to find. The Rhode Island egg people had a huge TV advertising campaign and I can still hear the jingle: "Brown eggs are local eggs ... and local eggs are fresh!"
