I'm using a bran and chick mash mix, and sprinkle the occasional helping of fish food flakes. I also toss in fresh veggies each day - something like sliced spud or something green. And they just love the bug gel. I like using this, too, as it's loaded with calcium. I've been using this mix for a while now and the crix mortality rate has plumetted. Until I feed them to the reps, that is...they don't last long after that - mhoo ha ha!
