Since I only have four chickens, we don't have a great abundance of eggs. However, I do like to give them to friends and neighbors from time to time. Since I only give them six, and because my eggs are blue, white and brown, I like to have a nice presentation for them. I have found a Clean Round Egg Carton, which shows off the egg colors and is a bit different from anything I have seen.
Got them at Randall Burkey.com - not cheap, but if you're just in it for the fun of it like I am, they are strikingly different from any I've ever seen!
