RSS Feeds

Hello

I am completely new to this theme and CSS, which I don’t know anything

about. I am kind of lost with this and I had to entirely delete the RSS Feed Icon from my Widgets because I was getting a blank page.

However, I was under the impression that if my website is

https://thehudsonriverchronicles.com

That my RSS Feed URL is

feed:https://thehudsonriverchronicles.com/feed/ (or)

feed://thehudsonriverchronicles.com/feed/

then I saw something else about

feed:https://thehudsonriverchronicles.com/entries.atom (or)

feed://thehudsonriverchronicles.com/entries.atom

can someone please help?

does this particular theme have its own RSS code?

Please help me?
