As Deborah said. You would see the best results from starting fresh. Get a 1 male to 3-4 females, that's what I did and it worked perfect for me, I eventually had more than I could use. A important part of having a healthy colony is feeding them properly. The mazuri food always worked for me and I never had to supplement with anything else.
Call your local feed stores and even in the other cities nearby and see if they can get and how much. I was paying $26 for a 50 lb bag from my local feed store.
