Most are perfectly healthy with one food item. I actually have trouble getting some of my snakes to accept other food items, which can be as insignificant as say...a different colored mouse than they are used to or replacing a rat with a mouse. In many cases, captive snakes can become easily imprinted on what food is. I suppose it is because their food is just tossed on them once a week or so, and they have no reason to be oportunistic and eat whatever they find. But as I said, it seems many captive snakes are easily imprinted. Whether prey moves or not, color, smell, shape, etc. That is why you shouldn't feed live mice as the snake will get used to live mice and will have to be fed live rodents its whole life(unless a nice amount of time is devoted to switching it back of course). It is the same principle with other food items. If you feed eggs, what if the snake becomes imprinted with them and refuses other foods? I doubt a diet of all eggs, especially most of the eggs you could get commercially, would be a good diet. But then again, a little variety here and there wouldn't hurt. But as you can see with other snakes, your snake will be perfectly healthy on a diet of strictly rodents. There are of course notable exceptions as some snakes will eat anything you toss in the cage, but I personally just stick with the rodents. Easy to obtain, feed, and pretty cheap. And they are just as healthy as any other food (provided they had a good diet before being euthanized).
