Separate species where possible. Some species may not be affected by certain diseases yet may serve as carriers of disease to another species that is susceptible. Vaccination programs for LT and IB are advisable for farms with a history of disease outbreak. Minimize free ranging of the flock by maintaining some form of confinement to lessen the chance for exposure. Maintain good ventilation while providing needed warmth.
Block drafts to minimize chilling and huddling.
Cold-stressed birds are more susceptible to disease than birds kept in a stable temperature environment. Nutrient requirements will increase during the winter months when birds have to compensate for low temperatures in their living quarters. Wild birds, particularly waterfowl, can serve as reservoirs of respiratory disease. When birds die from disease or unknown causes, rapid disposal of carcasses is important to prevent disease transfer. Mortality should be removed promptly to prevent scavenging by the remaining birds.
