Kill the "chicken"

Kill the "chicken" is an unmarked quest in Fallout 2.

Detailed walkthrough
The "chicken" that Rose gets her wasteland omelettes from is actually a very fearsome deathclaw!

To reach it, one must first subdue the dogs, then place some dynamite to blow up the rocks on the door.

You can kill it for 1000 (800) XP and a drop in Modoc town reputation. Rose will also no longer sell the omelettes. Killing Rose's deatchclaw while sneaking and without being detected will not result in a Modoc reputation drop. Upon asking for an omelet, Rose will simply tell the player that she no longer offers them because "some fool broke into our coop and killed our... chicken".

Bugs
When blowing the rocks and the dynamite blows the dogs as well, the game will crash.
