[jonnywestjjc]

Heya i recently just brought two Chinese Dwarf Hamsters (Poppy & Pickle) a week after owning them i was cleaning out the cage and i saw one humping the other, im sure there both females and they constantly are fighting now is this normal behavior

If you are sure they are both females then they are humping each because the other is in heat, or to show dominance. Its pretty normal with rodents.
