Chili Beer is probably the best way to go, imo. It doesn't have to taste like chicken, but spicy beer will work just fine. No need to go crazy trying chicken flavor in your beer, buttery beer is always bad. I would say a mixture of dried anchos, arbol, and habanero is the place to start.
If you want to try to get chicken in your beer, I would say boiling stock or bouillon. However, that is nothing I would try outside of a 1 gallon xbmt.
