they really are not good for anything other than pollinating would just go ahead and remove those 2 if you want you could wait till your other plant shows sex for sure but if its a female you really need to get rid of them by then unless you want seeds. they are wind pollinated and you would have to move them downwind a long ways to prevent pollination as the balls get more developed they will swell and release there pollen it will be like a powder and the wind could carry it quite aways.
