In the scientific literature poultry litter is usually used because chicken manure is a vague term. It could be argued chicken manure is any typical agricultural waste containing chicken excreta which is suitable for land application. Chicken manure is rarely plain feces as feces in avian species are typically combined with urine as excreta. Chicken excreta would be technically correct term for what this article is describing.

Also, research on poultry litter spans thousands of years so highlighting a point from one publication seems inappropriate. — Preceding unsigned comment added by Agriculturist50 (talk • contribs) 19:06, 10 August 2016 (UTC)[reply]
