Marek’s Disease Virus (MDV) causes tumorsand immunosuppression in chickens, and occasionally turkeys and quail. Infected flocks generally show clinical signs between six and 30 weeks of age; however, the disease can affect older birds as well. Not all infected birds show symptoms but will continue to shed the virus for life.Read More
While these charts contain many of the diseases that chickens may encounter, it is not an exhaustive list. Discrepancies in subcategories of a disease may exist. Some diseases are very difficult to diagnose without a veterinary post-mortem examination.Read More

Pullorum disease and fowl typhoid affect all poultry and various wild birds. Though virtually eradicated from commercial flocks in most developed countries, outbreaks still happen in backyard flocks, game birds, and wild birds.Read More

Darting beneath wings when they’re cold, and coming out to eat and drink, babies thrive on the mother-to-chick relationship. Brooder chicks must have appropriate heat sources, and humans must closely monitor them with thermometers and good judgment.Read More
