Bloat in Chinchillas

Hi,

I am worried about a new chinchilla I just got. I was wondering if she had bloat. Her stomach feels very hard, but she doesn't cry or whimper when I touch it. She is also eating well, pooping well and is still very active. I'm just worried that maybe the stomach could be the first sign. I feed them Oxbow, I switched from Carefresh about two weeks ago so that may be it? Any help would be great!

Thank you!
