Don't do that.
Use and external power supply for the servos.
Don't forget to join the grounds.

You absolutely have no hope of running 6 servos (servo, not servomotor) off Arduino 5V.
You don't have a hope with one, and you shouldn't do it at all as it risks frying the board.
You need a decent supply/LiPo pack(*) capable of 5A or more for the servos, just common the grounds.
Motor supplies and logic supplies don't mix.
(*) except most servos don't like 7.4V, so perhaps SLA 6V battery
