I have removed the chatter fields by using " feed tracking" option but i want to remove the chatter feeds based on the page layout (feed should be present for one layout , should not be present for another layout) . Is it possible in salesforce ? I just cloned an existing layout and didnt check the "Enable feed" check box . But still i am able to see the feed
The Chatter feed is a default component of Salesforce page layouts and is not possible to remove from them using declarative tools.
A Visualforce page can be used to display a page without the feed, but that is the only option available.
This previous question and answer covers it.
