Red Worms For Sale, We ship a Red Worm by size of worm,which are large. On the average our Red Worms are 350 worms to a pound. The reason why we don’t ship by thousands or use this term is because it can be confusing. To explain, a thousand grains of sand is one thing, or a pound of sand is a something else. Shipping large Red worms are like a chicken ready to lay eggs and stress less. Our Red Worm Farm Started in 1965.
