I'm thinking maybe it is.
I will be really bummed if it is. Here is an excerpt from craigslist, their prohibited list:
# Pet animal parts, blood, or fluids - including but not limited to stud/breeding service
#Non-packaged food items or adulterated food.
These are the 2 items I found on the list that ~could~ apply to chicken eggs. Why I was wondering because at first I did a google search for +craigslist +farm fresh eggs and when I clicked on some of the hits, I found that the ad had been BANNED! That's when I went and checked the prohibited list.
