Honestly, my first thought is that he's totally okay and not to worry.
Thing is, he's wild, been out there his whole life, and knows that whenit starts snowing, he best find a better place to be. If hedoesn't notice right away, believe me, the little guy is quiteproficient at digging, and would be able to dig his way out.
I wouldn't worry, Hun...I'm sure he's just fine, having gone somewhereless of a danger to a little bunny body like his.Remember...they have instincts that pass down from generations of wildbunnies. He's not a domestic bun that's been put outside inthe snow for the first few times, ya know?
I think he's just fine, and you'll see him when the snow startsclearing up, or even playing in the snow while it's stilldown!
Anyway, not that I'm an expert on wild bunnies...but that was my first thought in my general wild animal knowledge.
Hugs!
