Space use and navigation ability of hens at housing in the aviary for the laying phase: effect of enrichment with additional perches and genotype

open access: yesPoultry Science, 2023
: The present study tested the hypothesis that increased availability of perches could favor the adaptation and navigation ability of pullets of different genotypes at housing in a new aviary system for the laying phase.

Effects of Perching on Poultry Welfare and Production: A Review

open access: yesPoultry, 2023
Perching is one of the essential natural behaviors for avian species. Providing an optimal perching design (e.g., shape, dimension, and materials) for commercial poultry production is critical for maintaining bird health, welfare, and production ...
