[1.6.4] Replacing vanilla sounds

[DarkMorford]

Hi all. First time modder, and I'm starting by making a joke mod for my friends. (We play on an FTB Monster server, which is why I'm using 1.6 instead of 1.7.)

 

One of the things we want to do is replace some of the sounds—in particular, the chicken's hurt sound—with our own. I found some tutorials on adding sounds to my entities, but I can't figure out how to replace things in vanilla. Seems to me that it would require somehow going in and modifying the base code.

Actually, I'm not sure you need to do any coding at all to replace sounds.  Can't this be done as a resource pack?  I'm pretty sure my 10-year-old daughter replaces sounds and textures all the time without coding (of course she probably should be coding at her age!).
