Scared of seeds being from a hermster

I've got some seeds I pulled out of a bag. they are kind of wimpy and I've heard that smaller, more oblong seeds are hermie seeds. Does anybody know if this is true? The bud was very chronic, but I don't want to risk bringing hermies into my grow space.

no idea there i always keeps the nice beans i get out of chron sacks and toss the white ones if the seed looks healthy ide say grow it only one way to find out
