Rare chicken breeds can be more efficient at foraging their own foods to save on feed costs, or more sturdy in weather extremes such as cold or hot areas. Five years later, the project has taken major steps in providing genetically improved chickens to Sub-Saharan Africa. “Using the chick embryo model, we are able to examine the organism’s response to pathogen and increase sample sizes since using eggs, instead of chickens, greatly reduces the costs and biosecurity involved in these types of experiments,” Schilling adds. Meaning that M15.2 Fayoumi had the best resistance to the disease. More commonly, people raise chickens for the meat and eggs they can provide for their family.
