After forum post (swans etc thread) from Ed Keeble, including
just done some googling, and some info maybe of interest:
Guff here includes big chicken manure exporter on Black Sea coast; duck manure used in fish farming in China, Russia, parts of east Europe.
Fertilizer exporters:
from NIKKOM [Russia]

Nikkom site does mention “struction of pathogenic micro flora” – but still, interesting…

Our company manufacture organic manure, which is made of chicken dejection. It is use for corn, ripe, coya, fruit tree and so on. Our product is a kind of pure biologic manure.
News article, from 2000:
The largest and most up-to-date organic fertilizer plant ever built in China began operations recently in the port city of Dalian in northeast China’s Liaoning Province.
..
The plant was built by Han Wei, a private owner of China’s largest chicken farm, at a cost of 20 million yuan.
… Equipped with technology provided by the Shenyang Applied Ecology Research Institute (SAERI) under the Academy of Chinese Sciences, the plant is expected to turn out 100,000 tons of fertilizer this year, and has already received an order for 20,000 tons from Japan.
…
Han raises 2 million chickens producing 80 tons of fresh eggs a day, but the 200 tons of manure excreted by chickens everyday is a headache, so Han collaborated with SAERI to build the fertilizer plant.

As far as I’ve noticed amidst flurry of info, much of focus re potential role of poultry manure in sustaining (and spreading) H5N1 has been on chickens. But, turns out ducks important too.

A paper looking at integrated fish farming on one farm (in early 1980s) includes:
