>>A few Q's:
>>1) How long they last before they start to cacoon?
Depends on how much you feed them and at what temperature they're kept at. My experience is at 78 degrees being fed once a day, every day they will cocoon in about 3-4 weeks give or take a couple of weeks. Seriously though, I think 3-4 wks is about right.
>>2) How many crix will they replace? Like if my Beardie eats 10 crix a day, how many worms should I be feeding him?
As many as he wants in 10-15 minutes. The quantity depends on how big the worms are. For one thing, 10 crix a day is way too little amount to begin with. I'm thinking a 10" beardie will eat 7-10 1" silkies at a sitting.
>>3)Do they Stink?
Not in the least bit. The only thing that smells is the mulberry chow when you cook it.
>>4)what do they eat?
Mulberry leaves or Silkworm Chow, which is made from Mulberry leaves.

>>5) How many should I buy for a 12 week old baby? (so I don't waist them all 
Personally, I'd start off with small silkies, as close to 1/2" as you can get and buy the smallest amount you can. You want to be able to feed them all off before they either get too big for your dragon or start to cocoon. That is unless you want to breed them. Just keep in mind in the beginning you will probably have to go back to crix or something to substitute until you can get a good idea of how fast yours are growing and how many your beardie is eating.
