I hatched out some ornata a few years ago, they are very small, like new born Garter snakes. I assist fed with pinky parts but eventually lost them. Darren at Crystal Palace Reptiles had a lot of hatchlings last year, he had success using crickets. You may have to try various sizes. Hope that helps.
:My ornate paradise flying snake just laid 9 small eggs. As the eggs are so small it looks like the young are going to be as well. So what will be the best thing to feed them on. I know that in the wild they would take small young lizards. As I am in the UK feeding on lizards is not an option.
