Question about Silkworms

Once again I have a question. I went to a reptile show yesterday here in Michigan. I got my babies some small silkworms...but I negelected to ask if I should calcium coat them or are they OK just like they are. I bought this mixture there that you use everytime you feed them crickets..didn't know if I should put them on the worms or not. They really love those worms but I only give as a treat and let them eat those out of my hand. I wasn't sure of the fat content or anything about them. I should look it up but y'all are more knowledgable from experience.
When I got them the guy said they were only one week old making them 3 weeks old last Friday...compairing them in size to some at the show...they are a bit older or they are really big 3 week olds. But the past week they have become little eating pooping machines. I did get them a bigger tank...a 55 gallon Marty tank so now I can regulate the temperature much better for them.
Thanks in advacne on your info on Silkworms

I LOVE silkworms, the best feeder out there next to roaches. THey can be a staple, but it gets expensive. If you will be feeding dusted crickets too, you don't have you dust the silkworms. Mulberryfarms.com has a nutrition chart i think.
Many times dragons from different lines will have different growth rates. Or the breeder isn't giving them the attention you are, thus yours are growing faster.
