In 2013 I hatched out a couple of Black Magics.
Black Magics can vary quite a bit. At first glance it seems like all of them are triple genes, but 1 and 2 are incredible. I think the color of these hatchlings will be your deciding factor. I think 1 and 2 are without a doubt triple genes, the rest seem to be the same color as 1 and 2. If any of them are only Black Magics, I'd say number 4 is your best candidate. Maybe only 1 and 2 are the only triple genes. If 3,4, and 5 are not triple genes, they're the best Black Magics I've ever seen. I think once they have a couple meals and shed one or two more times it'll be easier to tell. I'm not 100% about this, so don't hang me out to dry if I'm wrong. Maybe I'd have a different opinion if I saw them in person or in different light. Here's some pics to help you out, if you need me to dig up some more old pics, I will.
Congrats!!! On such an awesome clutch and welcome back.
