Google Hunting for "rss.xml"

Noticed this in my error log

[Oaf357]

<snip>

<IP number> resolves to crawl10.googlebot.com.

The site I found this at was just launched on Friday and has never had a link to rss.xml.

The question is why is Google looking for this file arbitrarily?

Another question would be should I set up a 301 redirect to the appropriate RSS feed?
