Silkworm eggs are shipped in a Petri dish and will hatch 7-14 days after shipping when kept at 75-82F. Eggs come glued to the dish when ordered in smaller amounts, loose in one dish when ordered in bulk. You can order extra dishes if needed to glue eggs down, when ordered in bulk. Eggs arrive dark purple, a day or two before hatching the eggs will turn a light blue/gray color.
Allow all eggs to hatch before you offer any Silkworm food to them (24 hours after you see the first ones hatch). Once all have hatched, (if you look underneath the Petri dish, you should see mostly white egg shells.) grate a small layer of mulberry food over the top of the silkworms (use the smallest grate size on our silkworm food grater).
Allow the silkworms to crawl up on top of the food. 24hrs later transfer the silkworms, food, and all into the bottom of a silkworm keeper or similar open plastic tub (just bang the Petri dish upside down to empty it out.). Continue to feed daily; it's important that you allow the food from the day before to dry out before you feed again. You will see a rapid growth rate, after a week follow the silkworm care article. For best results DO NOT USE AN INCUBATOR AFTER THE EGGS HATCH.
