Western Hognose questions...

[Tigergenesis]

I've been told the Westerns are the best beginner Hognose. I plan to by captive bred. I'm considering getting a W. Hog, but have a few questions:

Are crushed walnut shells okay to use as a substrate? I plan to switch my Sand Boas to aspen, but right now I have some walnut shells to use up.

How difficult is it to get them to eat FT mice? I've heard they're easier than other hogs, but I'm wondering the likelihood of having problems.

How often should they be feed?

I've heard that they don't shed as often as other snakes - is this true?

I've also heard their feces are more runny and smelly than say...a Ball Python. Is this also true? Are their urates different as well?

I've read several online care sheets, but always like to hear from actual people and get their experiences. I just want to know what to expect.

Thanks!
