How I kept my silkworms alive...
3 things to get: 16 qt tub or any tub (bigger the better), gutter guard (from your local hardware store) and mulberry chow or leaves. I used the 20 ft vinyl Roll Gutter guard from Lowes for 3 bucks.
Poke air holes in your tub. Basically tape the gutter guard in the tubs slightly elevated and place all the worms and food in there. Therefore when they poop.. it goes through the holes. The less you touch/open the silkworm tub the better.. KEEP THINGS SANITARY!! I cleaned the poop about 3-4 days till a week depending on the amount of poop and refilled the food every 3-4 days as well.
Disclaimer: This is the way I did it successfully, obviously people have varying opinions. Do the method that accommodates you the most.
