According to the movie “The Best Little courtesanhouse in Texas”, the rate was “One Chicken, One Lay”. Yet, according to recent histories of the Chicken Ranch, this wasn't really true, even during the Depression.
The reason why it was called the “Chicken Ranch” is because the brothel was officially registered as a chicken farm to avoid trouble. Well, the brothel had to register itself as something, didn't it?
And – it's great story, and people love great stories.
