As I say, I have never shown eggs, but occasionally got to go to some of the major shows. A couple of years ago I made it to The National
Now I am a very "law abiding" personality, and I know you are not supposed to touch any of the exhibits and one of the very dark single eggs which had been entered looked so "old" that in the end all my inhibitions went out of the window and I just
had to pick it up. It had been entered by a well know and respected exhibitor, and if I said it was at least 6 mths old I would not be exaggerating
I certainly wouldnt suggest you do that but bearing in mind that eggs are still suitable for incubation for up to 3 weeks and they reckon most of the supermarket eggs are around 2 mths old, then I don't think it would be unreasonable to keep back nice looking eggs for a month or even maybe 5 weeks prior to the show
I would think that a cellar or cool dampish garage or pantry and store them in the fibre egg boxes, as if they are dark shelled it is imperative they are kept away from daylight which will fade the shells
Then having got a good selection of eggs to choose from, I have heard the experienced showers draw a line on some white lining paper and then set their eggs out on the kitchen table to select those nearest matching in size shape and colour. Make sure you rub your fingers over the shell, especially the narrow end at the bottom as that is where there are most likely to be shell imperfections.
Good luck
