Broilers do not spread evenly across their environment. Some may cluster near a wall, equipment line, or other boundary, while other areas appear relatively unoccupied. Shawna Weimer, PhD, University of Arkansas, explores the behavior of wall hugging and what it means to broiler production.

Research from the University of Arkansas suggests that giving turkey poults feed cues with green, moisture-rich feed attractants may help them find feed sooner, forage earlier and gain more weight during the first 10 days after placement.
Chickens are highly motivated to peck, forage, and explore their environment. Providing opportunities for birds to express these motivated behaviors, is a key component of animal welfare, and edible enrichments can be an effective way to encourage engagement with the environment.

In nature, fear protects animals from danger. In commercial settings, domestic laying hens are shielded from most fear-inducing stimuli, such as predators and unfamiliar situations. Therefore, fear serves as an aversive experience for the hens themselves and leads to undesired behaviors for producers.
The US-RSPE is a pre-competitive, multi-stakeholder organization focused on advancing sustainability across the entire US poultry and egg value chain. It designed the Sustainability Framework to provide the poultry and egg industry with a standardized approach to define and implement sustainability.
Woody breast, sometimes called wooden breast, has become a familiar and costly problem for today’s broiler industry, according to Cirenio Hisasaga, doctoral student at the University of California– Davis.
In the United States, the majority of laying hens are housed in conventional cages. However, there has been a shift towards cage-free systems. Cage-free systems can benefit laying hen welfare. Birds have opportunities to perform a full range of species-specific behaviors, including foraging, dustbathing, perching, and walking, which are restricted in conventional cages.
Poultry researchers use ‘affective valence’ — a positive or negative emotional response — as a measure of animal welfare. Tom Smulders, PhD, an evolutionary neurobiology researcher from Newcastle University, has studied whether hippocampal neurogenesis can be a marker of affective valence in poultry.
The International Poultry Welfare Alliance brings together expertise from across the value chain to develop Key Welfare Indicator Reference Guides for broilers, turkeys and layers, which align measurements and communications of welfare outcomes.
Research has uncovered much about how welfare impacts broilers’ physical and functional traits, but less is known about their mental state. A doctoral student at Virginia Tech studied fear and anxiety in fast- and slow-growing broilers, as well as the impact of environmental complexities.
