I've been buying
medium large rather than extra large or jumbo eggs for a while, based largely on intuition and educated guessing. I finally got round to researching it and it looks like my intuition was on target, if these claims are true:
Buying large eggs is cruel, shoppers toldhttp://www.timesonline.co.uk/tol/life_and_style/food_and_drink/article5884068.ece> “I prefer medium eggs,” he said. They taste better, are less watery and don't run off the plate.”
> “Selectively breeding hens for high productivity, whether larger eggs or larger numbers of eggs, can cause a range of problems such as osteoporosis, bone breakage and prolapse."
Surprisingly, even Kevin Coles of the British Egg Industry Council admitted that "when it comes to creaminess, consistency and flavour, size really does matter." (Egg-cessive? Large eggs are painful for hens to lay, claim experts. What's more they're less tasty. So should we stop shelling out for them? By MARCUS DUNK, Last updated at 8:17 AM on 12th March 2009,

Here's more:
Which Eggs Taste the Best?http://shelflifeadvice.com/content/which-eggs-taste-best"...according the egg guru Moses Wolfe of Petaluma Farms in Petaluma, California. If you’re looking for eggs with the best taste and the lightest texture, those would be pullet eggs, laid by hens less than 1 year old.
The very best qualities are those laid before the young chick reaches the ripe old age of 31 weeks. Because the bird is young, the eggs are smaller than those laid by the 1-2 year-olds. They may be pee wee, small, medium, or large eggs, but not extra-large or jumbo. These eggs not only taste great but make soufflés rise higher and omelets come out fluffier. Jumbo eggs are from older hens. These eggs, Wolfe explains, “age more quickly, losing quality, taste, nutritional value and recipe performance."
If I want large eggs I tend to buy duck eggs (or goose eggs, when they're available). Duck eggs are my favorite eggs taste-wise so far, I think, and they are supposedly richer in omega 3 FAs and nutrients than chicken eggs.
