Nice Pieds Tom. In response to your question, yes Fire Calicos have been produced. I hatched what I believe to be the first ones in early September, and yes there is a photo (see my forum post a few entries below yours). The Fire Calico is the orange snake in the top left corner. The ones I hatched are from the same clutch and are low white. I have not taken much in the way of photos because I wanted to wait until the colors really came in... which are just now starting. In a couple months I think they will be insane. I'll try to post a better photo this weekend.
Hope you hit good odds with your clutch. I'd like to see some more to compare.
All the best,
Dan Wolfe
