Pastured poultry also known as pasture-raised poultry or pasture raised eggs is a sustainable agriculture technique that calls for the raising of laying chickens, meat chickens (broilers), guinea fowl, and/or turkeys on pasture, as opposed to indoor confinement like in battery cage hens or in some cage-free and 'free range' setups with limited "access ...

[18] The benefits of free-range poultry farming include opportunities for natural behaviours such as pecking, scratching, foraging and exercise ...

The most common commercial breed in the United Kingdom and the United States is the Pekin duck , which can lay 200 eggs a year and can reach a weight of 3.5 kg (7 lb 11 oz) in 44 days. [ 34 ]
Sewage treatment plants mix these organisms as activated sludge or circulate water past organisms living on trickling filters or rotating biological contactors. [ 5 ] Aquatic vegetation may provide similar surface habitat for purifying bacteria, protozoa, and rotifers in a pond or marsh setting; although water circulation is often less effective.
