Eggs are not chicken?

There’s the nub of your problem. The oocyte NEVER WAS meat OR a chicken. It had the POTENTIAL to BECOME a chicken, which would have had the POTENTIAL to become meat (most civilized people not considering chickens “meat” until the chickens are dead), but that potential was lost when the egg failed to be fertilized. It lost the POTENTIAL to become a chicken when it passed the point at which it could have been fertilized. At that point, it became, now and forever, JUST an egg.

If I’m understanding this correctly, it’s irrelevant. We’ve moved on from the “parts is parts” argument.

We know. We’re saying you’re mistaken, in both a religious sense and a scientific sense. You just don’t want to hear it.

my point is simpler. don’t know about the jewish diet, but there have been vegetarians from a long way back (BC), and it’s my WAG that there’s three camp.

camp A - chicken egg = chicken baby, no eat
camp B - meat is wild game that is dead; egg is like milk, can eat
camp C - i want my egg, yum yum. no egg = no vegetarians

i guess the majority won…

Is the skeleton meat or bone?
Is cartilage meat or gristle?
Is blood meat?

For the majority of people, meat is flesh, which an egg is not.
(And, yes, in English “meat” has had a number of different meanings over the years, including as a generic synonym for “food” (meaning celery and ice cream in that instance would be meat), but for the purposes of every dietary law with which I am familiar, meat translates a word meaning flesh–skin or muscle–neither of which are components of egg.)

But one can also eat fertilised eggs, without realising it. IIRC ultra free range eggs (eg from people’s hens living in their back yard, or small individual farmhouses) could be fertilised.
