I have never heard of just raw eggs as a diet, but you can do some reading on our sister forum English Bulldog News, it's been around a few years and has a lot of diet and nutrition info. Frenchies and bulldogs share many of the same skin issues.
Here's a link to that forums diet and nutrition posts:

Hopefully that will help you, please let us know how it goes.
