I'm not the best at these, but I believe that it would be something like this:
/macro chicken "powexecname Taunt$$emote 'chicken'"
The 'chicken' (including the quotes) would come out, and be replaced with the actual emote name, since I can't remember it, sorry.

Thank you, I'll try it when I get home. 
Anyone good with macros?
Could a macro for taunt do the chicken emote?
I remember replacing the tricorder on aid self with roar a long time ago from a forum post.
