I suppose you could say "sex" but since both worms have sperm that they swap, and then both worms lay eggs and neither one ever does the dishes, is it really sex?

After breeding, each worm will lay about one egg every week until its sperm supply is depleted. With the right conditions (temperature, food, space) the capsules will hatch in between 30-50 days. It will take another 50-75 days to reach breeding maturity. There is a lot of info out there that indicates worm population will double every 60 days. I have found that that is not the case. Your worms will breed at an alarming rate, once you have a large population of breeders. The mature worm population laying one egg a week for about 52 weeks, each egg hatching 3, plus young...you do the math.
