I always found it a bit frustrating to copy/paste feeds to feedly manually, so I stumbled upon this workaround, it works quite well, as there is no official chrome extension of feedly:
1. Install RSS subscription extension (https://chrome.google.com/webstore/detail/rss-subscription-extensio/nlbjncdgjeocebhnmkbbbdekmmmcbfjd)
2. In options (chrome://extensions/ – click on options near “RSS subscription extension (by Google)) : click on “add…” button, put “feedly” in “description field and “http://www.feedly.com/home#subscription/feed/%s” in URL field.
3. Select feedly and click “Make default” (or optionally if you use only feedly, delete the other options it will be immediate when you click on icon if you have only one reader)
4. It’s done, now when visiting a website which provide RSS, you have a RSS icon in the multibox, clicking on it open Feedly and at the top of the feed, you have a “+Add” button letting you add it to feedly. Clicking on it open a dialog which allow you to select the categories.

After a click on the „star“ the feed URL is pushed to feedly, and you just have to „+feedly“ there – pretty easy.
