You should have an incubator in your inventory, put the egg in that and take a walk of the required distance to hatch a pokemon.
Found it, I had to go into the Pokémon menu and swipe left to show the eggs.
I assume the rustling in the map is meant to indicate there is a Pokémon in that area? I walked to one of these rustling but never found anything.

Will the UK release reset progress? Not sure if it want to put to much time into it if so. I take the long way home from work just for this game lol, there is a ton of pokestops and gyms, but the short way home has nothing!
