Fuzzy problems.

Ok so I decided to sprote some sunflower seeds for my chickens , I put them in a bottle and washed them with warm water letting them soak a little up then draining off the excess water and sitting them in the window sill. Two and a half days later I have sprots but there is a little spot of what looks like fuzzy mold of some sort ... Mold is not good for chickens right? So do I have to throw the sprots out (its gonna drive me nots I cant spell sprote but anyways) or can they still have them? How do you do this without getting fuzzy hijackers?? THanks in advance.
