it depends on the bird, sometimes their under attack by bees or ants, so they try to fly out or run, or their pushed by siblings, or they try to fly because their parents are calling them or coaxing them out of the nest. occasionally the parent will push them out as well to get them to fly. I have seen all of thoes things on animal shows. Animal planet is a good source to learn from. Sometimes it is because a human toched the bird/chick as a result the mother won't want it any more. Or because of a strong wind that blew it out of its nest.

A cuckoo does not make a nest, a cuckoo will lay an egg in another birds nest, the other bird will then care for the egg and chick as if it was it's own.
Either a nestling, a fledgling or a chick.
No. The nest may not really be abandoned even though it looks like it. Unless you're talking about domestic fowl like chickens, then, yes, you should remove the chick to a location that it can find food in.
Ummm...... I suppose 7 are left.
because she can go dget food for him/her.
A female cuckoo typically lays one egg per day until she has a full clutch of about 12-14 eggs. She then seeks out the nests of other bird species and lays her eggs in their nests, leaving them to be raised by the host bird.
The Cuckoo is notorious for laying an egg in another bird's nest, leaving the host bird to raise the cuckoo chick. Once the cuckoo chick hatches, it instinctively pushes any unhatched eggs and chicks out of the nest, leaving the cuckoo chick the sole occupant.
