"Meat (or rather, animals) also consume a lot more resources to produce the same amount of available-nutrient output."
Depends on how it's raised. Grain-fed meat, sure. Grass-fed meat, not so much. People can't digest grass.

Only 3% of beef in the US is grass-fed. For chicken, the equivalent would be "pastured", and I bet it far less than 1% (I've never seen it for sale in supermarkets and I know you have to join a coop or something to get it).
