try it. you might be the creator of a new hybrid. whats the worse that could happen? they dont cross, or the offspring are sterile. if youre wondering, then try it! the two could theoretically meet in the wild. idk if they would breed but im pretty sure their range and habitat mixes. who knows maybe theres already rainbow x rosy boa hybrids out there.
What's the worst that could happen? You could have an entire clutch that fails to thrive and all have to be put down...
