I have actually seen that big-eyed condition before. There was an 09 pied male for sale on kingsnake and they were letting it go for about $500 less than pieds were worth at the time. They were suggesting that despite his deformity, he still possessed the pied gene and was worth breeding. I wasn't so sure about that...
Anyway, I am very interested to know whether the babies are all male or all female. I at first assumed they must be all female because I didn't know about the ZW chromosome system, but now I'm not sure. If we knew what gender they were, it might shed some light on what chromosome system ball pythons go by. Interesting stuff!
