I raise my own, just started recently. It is kind of neat, my son (he is three) loves it, my house is kind of like a science project. You need to let your silks grow to cocoon, they will usually stop eating for about 3 days prior to cocooning. I put some egg cartons and empty toilet paper rolls in there, they seem to like to cocoon in those. It takes anywhere from 2-3 weeks for them to emerge from the cocoons. They don't fly, and their only objective is to find a mate. The female is born pregnant, so hopefully there is a male around for her to mate with, otherwise she will lay unfertile eggs. They usually mate, and it takes about a day, and afterword the female will immediately start laying eggs. The eggs will hatch within a week usually, sometimes they don't hatch at all (the fertile ones turn a purplish black after 3 days or so),but you have a better chance and a higher hatch rate if you put them through a "winter". I refrigerate them for several weeks, at the least 3, then put them in the incubator, set at between 75-88 degrees. I keep it around 83. The eggs will hatch within 7-12 days. So far, I have been lucky and had a high hatch rate. I don't feed mine mulberry leaves, as once they get used to them, they will not eat the chow, and of course I do not have a mulberry tree. I think the chow works just as good, and as I stated in another post, I don't think I have ever had a silk die on me. I have had unhatched eggs (not many), and maybe a couple of neonates that did not make it, but for the most part, it is really easy and fun, especially if you have kids, it is really a learning experience for them (you too!)
