· Perform stressful activities (such as moving, handling or vaccinating) early in the morning.
· Provide shade to hutches—add supplemental shading if needed.
· Promote good airflow in and around hutches. In enclosed facilities, if natural cross-ventilation is not possible, then a total air exchange every two minutes through a mechanized system is a must.3
· Control flies. Implement practices to breakup fly life cycles.
