Marek's Disease is one of the most common flock illnesses. It is economically devastating for unvaccinated commercial flocks, and emotionally tough for small flock owners with unvaccinated flocks. However, with attention to flock health and vaccination of new arrivals, it can be easily managed.

Avian Influenza is a highly contagious poultry virus that has the potential to cause large financial losses to the U.S. poultry industry. A highly pathogenic strain (HPAI), H5N1, last hit the U.S. in 2014-2015, and was considered the nation's largest animal health emergency. Over 200 cases of the disease were found in commercial flocks, backyard flocks, and wild birds. More than 50 million birds were affected and subsequently died or were euthanized on more than 200 farms in 15 states.
