well explained, and there's also the issue of chicks - farmers don't generally hatch their own eggs but buy chicks, and it's easy the big companies to manipulate that supply chain, indeed I believe there are ownership and licensing deals in place that favor the big producers.

Good point. There may be deals like x percent of your stock will be buyed by us. If I'm the stock owner, i would gladly agree and reduce the price, if x is bigger for one buyer than y+z+w percentages of three buyers. I would have a guarantee to sell more of my chickens for sure at once and would reduce the uncertainty of even finding three different buyers.. but this reduces the stake holders (different sellers) in the market and the big one can dictate the prices and produce amounts at will.

Bigger is always winning.
