You can't say that all crix are always safe, nor can you say that a particular retailer sells only bad crix unless you do a double blind study that gets published in a peer reviewed journal. Even then, you couldn't make such broad conclusions. Anything is possible. Death and taxes, nothing else is certain. Anecdotal evidence is frequently powerful stuff, but it's just silly to state, with such authority, that your experience makes you the cricketmeister and any other opinion is flatly wrong. I fed my mantid crix once that I feel certain made him ill. I fed him moths, discarded the crix, he got better and now he eats crix again. What does that prove? Nothing. I bet that altogether the people on this forum feed more crix, collectively, than any other food. They can't be all bad but they can't all be good. I can't believe I just wasted the time it took to write all of this.
