A fledge
7 to 10 days
Since roadrunners are a bird a baby would be called a chick.
Baby birds mostly fledge or leave the nest in mid/late Summer.
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.

The cast of Cardinal Baby - 2008 includes: Ozzie Smith as himself Audrey Whitby as herself
Tawny Frogmouths fledge at 25-35 days.
They can fly as soon as they fledge. The parents will fly and swoop with them though.
After about three weeks they fledge, or take their first flight. They may stay in the nest another week.
Probably about 1 month. I had before and it took about 3/12 weeks for it to fly. I found it at the pet store.
