Only if you get one from a pet store can you keep a baby bird ,but
not a wild one.
until the bird is able to hunt ,fly and fend for itself.
You can try to save it. Keep it warm with a heating pad under it, keep it out of drafts, and feed it.
the baby bird is called nestling
well if that baby bird is your pet and it can nearly fly,....... no. Trust me i have a baby bird for a pet.

Assuming you encounter one, pretty much the same way you'd care for a baby bird; keep it warm and feed it constantly.
they become migits and when they turn to bird their feather get bigger
No, a baby bird cant, but if it is crushed it can.
The baby bird eats it. It's important fo baby birds to get nutrients, and the yolk contains the things a baby bird needs to grow proplerly.
It has to adapt to its surroundings and has to keep a low profile so it doesn't get spotted by predators.
At birth, a baby has approximately 300 bones. It depends on the baby.
I would think the mom bird teachs the baby bird to fly so the baby bird knows how to fly and take care of the baby the bird will have when it grows up so it can fly and take care of itself and the baby it has if it has one ^____^.
