Red worms are hermaphrodites which means they are both male and female (although it does take two to tango). They produce eggs or capsules from the saddleback which you will see on the 13th segment on their bodies. The egg looks like a tomato pip and starts off a yellowy-green colour and as they age they go a brownish-red. Each one will have between 5 and 15 tiny worms inside, and these take about 10 days or so to hatch out. Buy Our Composting Worms Shop Our Wormery Products Complete Video Guides To Worm Composting
