How much research have you actually done? Because if you had done any you would know that they happily take rodents ie mice. It's difficult to say much more as being an "egg" your location doesn't show. If you are in the UK, you will only be able to readily get hold of western Hognoses. Very, very rarely, Mexicans can be found. Having kept and bred both (I was the first person I the UK to breed Mexican hogs), they will take mice.
Tri coloured hogs should also take mice. That leaves eastern and southern hogs, if you are in Germany or the US, as they appear unavailable anywhere else. Again, as cb animals, these still readily take mice.
Naturally, they are mainly toad eaters (not frog), but cb specimens, once the breeder gets them going, take mice and never look back.
