Baby blackbird's are equipped to fly the nest very soon, before they can fly and gather food. They will flop out and become fledglings.
Baby blackbirds typically fledge, or develop the ability to fly, about 2 to 3 weeks after hatching. During this time, they grow strong enough to leave the nest and begin practicing their flight skills. Once they fledge, they may still depend on their parents for food and care for a short period before fully becoming independent.
1 year
10 days
Between 10 and 19 days is commonly quoted amongst birdwatchers but eggs hatched in aviaries invariably take 14 days. While a longer incubation period for eggs laid in habitat could possibly be the result of disturbance, a shorter incubation period than 14 days is exceedingly unlikely.
It takes about 13 days after hatching before a Bluet Robin to fly from the nest. This is after the mother has left them.

Sparrow chicks typically fledge, or leave the nest, about 2 to 3 weeks after hatching. During this time, they grow rapidly and develop the necessary feathers and strength for flight. Once they fledge, they may still depend on their parents for food and protection for a short period before becoming fully independent.
Baby cardinals typically fledge, or leave the nest, about 9 to 11 days after hatching. During this time, they are fed by their parents and grow rapidly. Once they fledge, the young cardinals may continue to be fed by their parents for a short period as they learn to forage on their own.
Blackbirds reproduce by laying eggs.

There is no specific collective noun for blackbirds but any collective noun for birds will do; for example a flight of blackbirds or a flock of blackbirds.
