Without other stressors to skew results, altering stocking density (SD) within common ranges does not affect the well-being of layer chicks being transported from hatcheries to pullet-rearing operations.
Formaldehyde fumigation is a conventional method used to control total environmental microbial counts in the hatchery. However, according to Christine N. Vuong, PhD, University of Arkansas, this method does not differentiate between beneficial or pathogenic microbes.
