I highly doubt a python of any sort, especially the retic, would go after a quails egg. Imo, it's not equipped to do so. The only snake that would be interested in eating is the African Egg Eating snake.

Although, that video is pretty cool, seeing as I've never heard of rat snakes eating eggs. But what I said earlier, it's probably very improbable that they would go after eggs. The only one with actual access to them would be the GTP, and I've never heard of them eating eggs.
