So it's a question of semantics rather than DNA?
Since we habitually call things without calcium shells, eggs, it must be the word in front that becomes the defining one.
If you call it a chicken's egg then it needs to have been laid by a chicken because the egg belongs to the chicken that laid it. However, if you call it a chicken egg, it has to contain a chicken, but is free to have been laid by not-quite-a-chicken?

I think that we would all agree that the protochick came before the chicken or the egg, but did the protoegg come before or after the protochick?
As mammals also produce eggs, but don't usually expose them to a harsh environment, they dispense with the need to encase them in calcium. Could it just be The Daily Mail got it wrong (again)?

2) Does it have moving parts? Yes, definitely.
3) Is it electric/electronic? Not necessarily.
4) Is it a form of transport? Yes.
5) Does it have at least 3 wheels? Yes.
6) Is it normally found on roads? No.
7) Is it found on farms? No. Chickens and eggs are found on farms.
8) Does it need rails? No.
<Geg: Yes, it is semantics. The rest of your argument is (at least in part) circular, and therefore invalid>
<Skidmarks: It is not that mammals ever dispensed with the calcium shell - they never developed the ability (*). Birds did. The common predecessor, reptiles, neither have nor had calcium shells (*).

Ahah! I did not actually write that they dispensed with the calcium shell. They dispensed with the need. A totally different kettle of fish. (Also an category of animal that avoided needing calcium.)

Hmm, an engine, at least three wheels, moving parts, not necessarily electric, not found on roads...
