Question

Is there a way to make eggs hatch quicker in gen 5?

Answer 1

Ways to make eggs hatch faster, Gen V

• Pokemon in party with Flame Body
• Pokemon in party with Magma Armor

And... it's still the same as in the other Generations. Just those two ways, sorry.
Ride on Skyarrow Bridge! It doesn't actually make eggs hatch faster; it is just straight and easy to ride/run on, so that's my recommended place to hatch eggs.

Answer 2

Isn't it the same method. Keep a Pokemon with the ability Flame Body or Magma Armour in your party and that decreases the number of steps that you need to take for the egg to hatch.
