Sometimes the worms are not too excited about leaving their home tray and traveling upwards. First, give them some time to migrate up. If you have just set up your second tray, give them at least two weeks to migrate and acclimate to their new "home tray". If after two weeks your worms haven't made the move, you need to take a look at the second tray. There could be a food product that you have added that they don't like. Dairy products, meats or citrus products are items you should avoid. The bedding could also be too wet or too dry. If the bedding is too dry, add some water or green food scraps (fruit, vegetables etc). If the bedding is too wet, add some shredded paper or other carbon-based food scraps (corn cobs, coffee grounds etc.) to soak up excess moisture. A careful balance of food, moisture and temperature is important to keep your worms happy and healthy.
