I agree with what everyone else said.
Have you had a storm recently?
I was at my friends house a couple weeks ago and their then 10 week old lab puppy was in the crate when we had a helluva thunderstorm. I could hear him howling and whining and I went to check on him and he had had diarrhea. I think the storm scared the poop right out of him!
poor ginger.

if you have trouble getting the smell out of the crate (I know when Keegan messed in her crate or has diarrhea in the house - it must just stick to my nose b/c I feel as though I can smell it for DAYS) cheap toothpaste and cheap mouthwash gets the poop smell out.
I just scrubbed it really well with cheapie toothpaste -hose it off - poured cheapie mouthwash on the floor of the crate let it sit for a couple minutes then hosed it out and let it air dry.
