It is extremely easy to raise silkworm. All you need to do is to put them in a paper box with unlimited supply of mulberry tree leaves. Although you have to use the very young leaves for the newly hatched silkworms, or they won't be able to eat it. As they grow, you need to add more mulberry tree leaves multiple time a day, because they eat like pigs. All it takes is about a month or so for them to start building cocoons. Their life span is short. All they do is to eat, grow, build cocoons, become moths, lay eggs, roll over and die...all in less than 2 months. I feel sorry for them. Life like that must suck, no TV, no internet, no party, etc.
