Is there any particular reason why you are so keen for large eggs and if so, why not consider duck or goose eggs or even ostrich. Remember that those extra jumbo eggs have to be laid by a hen and the larger the egg the more potential for reproductive complications. The more market there is for jumbo eggs, the more the industry will breed for them, perhaps at the expense of the long term welfare of those hens. Spare a thought for those poor birds that have to pop those whoppers out each day and consider eating an extra medium sized egg instead.
It is the same with meat production. Farmers are breeding calves that are so monstrous that the cows cannot naturally birth them and the calves have to be physically jacked out of them or C sections are necessary. Selective breeding should be tempered with compassion for the animal involved. Things have gone too far in my opinion and it's so easy to accept the current status quo and not see them for what they really are.... which could certainly be considered animal abuse... and realise that we are pushing the natural boundaries too far.
Now stepping down off my soap box
