Feed Links Produce Error

The following links are at the bottom of my WordPress page:

feed:http://www.yourhomeincome.com/watkins-online/feed/

feed:http://www.yourhomeincome.com/watkins-online/comments/feed/

If I go to those links, I get a “this page does not exist” type error.

If I take the “feed:” off the front, the link goes to a page with a bunch of code.

How do I fix this? Thanks!
