Chicken advise newbie.

Hi i am planning on keeping a couple of chickens .I am converting a unused
dog kennel.I know the hen house/run are best placed on grass and better
still to have two locations so you can move them to give the ground a chance
to recover.How important is it to have the house on grass or for the hens to
eat grass?I am thinking of using a spare concreted area putting down a
layer of chipped bark,i am thinking this will stop foxes digging into the
run,the area can be seen from the conservatory so can keep an eye on
them,not to far to walk and maintain/my prefered location.I could put them
at the bottom of the garden but it is 200ft long so cannot be seen from my
house,this is a soiled area.Any advise is appreciatted .
Thanks Keith
