I haven't yet, I'm wanting to get ahold of some quail eggs for my japanese rat snake but am having some trouble locating any. Japanese rat snakes have a special vertebrae that cracks egg shells, so its probably a good idea to provide something that they're specialized for. She does eat mice and baby quail eagerly enough.
Right now, she's way too small to handle chicken eggs. I don't know if she'll ever be big enough for them. Little noodle.
