Answer:
I'm no expert at poetry, but lemme see...
Explanation:
The second line says that many birds will hatch from the eggs. That is something true. Birds hatch from eggs.
Fourth line, I am not exactly completely sure what it means but I know that it says that they will grow feathers soon. That happens in real life
Something line(I gave up on counting) says this: Flying, and over Lands with mutual wing. That happens. They fly over land and sea, with a wing that used to have no feathers sort of mutated I guess into one that has it.
There are probably more, so if you need more lemme know.
