Rabbitts spraying urine?

i have just aquired a buck rabbit and already have what i believe to be a doe, i let my doe out of her hutch this morning and she went around the back yard pooing and flicking urine all over the place and up against the hutch of the buck, and rubbing herself along any surface just like at cat, after 20 mins i put her into her cage and let out the buck, he did exactly the same thing, so my question is do i have two buck rabbits or is this normal behaviour? also would it be safe to put them together, not sure if either have been neutered,
