I had a long post typed out with all kinds of useful advice in it, but I thought to myself, "Self, why would you help someone become a bigger and better rat breeder? That is what you do. You certainly don't want your trade secrets getting out."

So, then I deleted my post and typed this instead.

Here is the one bit of advice that I will give you.

If you don't want to pay for labor, handling, freight, fuel, tolls, insurance etc...pick up your own feed LOL.

Also, be nice to your competition. If you don't like them don't hang out with them. However, when you light a fire under someone's back side they may surprise you and put you out of business LOL. Let sleeping dogs lie.
