Quick answer
Rare eggs are opportunities with scarce or contested availability; rarity, size and mutation are separate qualities.
What is confirmed
The official game loop confirms that players steal eggs, hatch pets and compete with other players. The official description also distinguishes rarer eggs, pets, sizes and mutations.
What still needs a live check
The developers do not publish a complete public table of spawn odds. Community timer claims and ‘secret egg’ methods should not be treated as guaranteed unless reproduced and dated.
Best way to use this information
Learn the server refresh rhythm, keep a safe return route and evaluate the live egg rather than chasing an old ranking. Record location, server time, visible shell traits and hatch result for any unusual find.
