I first heard a variation on that joke in the 1934 film, "Viva Villa." One of his guerrillas was trying to explain socialism to another by saying that if a man had two houses, he'd give one of them to another man. The second man didn't under stand so the first ties again using Bulls. Still no success so he keeps trying with horses, then goats, then finally chickens.
With the chicken analogy, the second man finally understands, but doesn't like the idea. When asked why he replies, "because I have two chickens."

I've looked for a video clip of that scene, but had no luck. I'd keep it handy.
