Being that I'm a personal friend of Kevin's at NERD, and have been a guest at his facility on three separate occasions for almost a week each time - I can tell you that NERD does feed live. I know this, because I've fed his ball pythons, and we fed them live.
He's full of it, and he knows it, which is why he has an excuse for what you print and an excuse for not coming on here. Every large breeder here in the States has fed live. There are a handful that feed f/t, because they simply don't care to deal with breeding their own rodents, and f/t is easier to get in large volumes.
