Anyone heard about using pig chow for the roach chow base? I picked up some dubias from a friend and he uses a 50lb bag of pig pellets mixed with a little bit of Repashy food, I think it was 1tbsp crested gecko MRP per pound of pig chow. He gave me some and they go absolutely nuts over it, eating it faster than I ever seen them eat anything. I am looking at Family Farm Pig 14 (what they sell near me), looks like lots of good stuff in it (grains, molasses, alfalfa, lots of vitamins), but one thing that I find odd is it says it has extra copper. Its cheap at $16 for 50lbs. Anyone be worried about the extra copper?
