If the received wisdom is that a larger chicken industry will increase the price of chicken feed, then my prior is that it's true in the short term, but not the long term. Chicken feed might be in finite supply, in which case Cost might grow with chicken industry size, but there are other reasons I can imagine Cost might shrink with increasing chicken industry size (listed in original article) and I don't have enough confidence about any of these factors to break my prior that Cost at industry size 2X is ~Cost at industry size X.
