* A specific TV show: If you're asking about a show called "Feud", there are a few different ones, including a popular series on FX called "Feud: Bette and Joan" (which was about the rivalry between Bette Davis and Joan Crawford).
* A general concept: If you're asking about "feuds" in general, there's no specific channel for them.
Please tell me:
* What kind of "feud" are you interested in? (A specific show, or a general concept?)
* Is there any other information you can provide about this feud? (For example, what is it about, or who are the people involved?)
With more information, I can help you find the channel!
