Have had my large egg for about 8 months now and am finally breaking down and going to buy another. I have been torn between purchasing a large or a medium, as price really is not an object portability comes into play. I intend to have it in a nest but built into a table that I can roll it in and out of, but I may on occasion want to take the egg places. I guess the question would be is there a safe way to transport an egg in the back of a truck while it is still in the nest? If the answer is yes, I'll be getting a large, if the answer is no, I guess I will need to go with the medium.
