Evaluation of Maryland Backyard Flocks and Biosecurity Practices
2013
SUMMARY Domesticated poultry are susceptible to infectious and zoonotic diseases and can serve as a transmission source to other bird and human populations. In recent years, the number of noncommercial poultry has been on the rise in the United States. To evaluate potential risks of this growing population, a descriptive epidemiologic survey was conducted among Maryland backyard flocks. Owner and flock demographics were characterized as well as management practices such as husbandry, human-to-bird interaction, bird exposure risks, poultry health status, and biosecurity.

Just over half of the owners (51.2%) kept chickens only, with the remaining backyard flocks consisting of chickens, other gallinaceous species, waterfowl, or a combination.
