Trouble with RSS feed – jumbled mess of code

Hi,
My feed is not working – all I get is a bunch of code when I access the URL.

my site: http://www.hazelandagnes.com

my feed: http://hazelandagnes.com/feed/atom/

I tried the feed validator, but I wasn’t quite sure what to do with it.
http://validator.w3.org/feed/check.cgi?url=http%3A%2F%2Fhazelandagnes.com%2Ffeed%2Fatom%2F

If it matters, I just deleted my feedburner feed when this became an issue.

Thank you!
