Dasypeltis Medici (East African Egg-Eating Snake)

I know of someone who has one of these, and I was a little curious about their diet. Does anyone have any information? Is it true they can only eat unfertilized eggs? Any help is appreciated.

I did a search and from what I read they are strictly egg eaters and usually eat quail eggs, I didn't see anywhere where it said they had to be unfertilized though.

You say you know someone who has one - might I ask where he got it? I've been looking for them for a little while, but finding someone selling one (or even a price) has proven tricky.
