Improved Kienyeji chicken has several advantages over the traditional Kienyeji chicken. Some of these advantages include:

1. Higher productivity: Improved Kienyeji chicken breeds have been selectively bred to have higher egg and meat production compared to traditional breeds. This means that farmers can get more eggs and meat from their improved Kienyeji chickens, which translates to more income.
2. Disease resistance: Improved Kienyeji chicken breeds are bred to be resistant to common poultry diseases. This reduces the need for farmers to use antibiotics and other drugs, which can be expensive and can lead to antibiotic resistance.
3. Faster growth: Improved Kienyeji chicken breeds have a faster growth rate compared to traditional breeds. This means that farmers can sell their birds at a younger age, reducing the cost of feed and other inputs.
4. Better feed conversion: Improved Kienyeji chicken breeds have better feed conversion ratios, which means that they convert feed into meat or eggs more efficiently. This reduces the amount of feed needed to produce the same amount of meat or eggs.
5. Improved meat quality: Improved Kienyeji chicken breeds have better meat quality compared to traditional breeds. The meat is tender, flavorful, and has a lower fat content.
6. Diversification: Improved Kienyeji chicken farming provides farmers with an opportunity to diversify their income streams. Farmers can sell both meat and eggs, which can be a source of income for them.

Overall, improved Kienyeji chicken breeds offer farmers an opportunity to increase their income, reduce the risk of disease, and produce high-quality meat and eggs.
