@HopelessDemigod @N3VEM I was curious about standard chicken-per-acre density, and now I will leave you with an important fact:

"At a stocking density of 50 hens per acre, the hens will add 2.5 tons of manure per acre per year, equivalent to 106 pounds of nitrogen, 30 pounds of phosphorus, and 61 pounds of potassium. ... Fifty hens per acre has been considered to be the free-range sweet spot for over 100 years."

I shit you not:
