What was the 364% grows caused by?
Is this due to selection (like a modern corn we have) or antibiotics being fed to the livestock? (of course, the answer is both but maybe I am missing something).
And a question to a no-tasty-chicken-in-markets adepts, have you (or your farmer/supplier) ever tried to take a modern-genetics chicken and feed them with no antibiotics or other grow-stimulators - what is the taste?
