Mitigating Particulate Matter Generation in a Commercial Cage-Free Hen House

Transactions of the ASABE, 2019
Abstract. Compared to conventional cage production systems, cage-free (CF) hen housing offers hens more space and opportunities to exercise their natural behaviors (e.g., perching, dust bathing, and foraging). However, CF housing poses a number of inherent environmental challenges, among which are high levels of particulate matter (PM) and ammonia (NH3)

The Impacts of Stocking Density on Behavior of Pullets Reared in Cage-free Housing Systems

2023
   There is a clear need for more research detailing how to manage birds in cage-free housing systems. Although management guides for birds in cage-free systems focus on adult hens, previous research has established that the pullet phase is important to success later in life.

THE IMPACTS OF HOUSING DESIGN ON LAYING HEN BEHAVIOR: A COMPARATIVE ASSESSMENT OF TWO CAGE-FREE HOUSING SYSTEMS

Due to increasing legislative and societal demand for humane egg production, an increased production of cage-free eggs is inevitable. Past research has focused on the impact of cage-free housing systems (CFS) on laying hens' performance, health, and space use; however, limited studies have examined the impacts of CFS on the behavioral activities of ...
