Trends in Food Production
• Organic
• Free Range
• Produce local/Eat local
• Shift in Poultry Population
![Page 3: Basics of Poultry Health and Management - · PDF fileBasics of Poultry Health and Management Mohamed El-Gazzar, DVM, MAM, PhD, DACPV Assistant Professor, Poultry Extension Veterinarian](https://reader031.fdocuments.net/reader031/viewer/2022022005/5aafd03e7f8b9a6b308dc6e9/html5/thumbnails/3.jpg)
Urban Chicken Ownership in Four U.S. Cities
• Denver
