Roosters needs are not much different than that of hens. Things to keep in mind: 1. Roosters pecking order is very important to their health, both mentally and physically. 2. Roosters live to protect and lead the flock and will gladly die to defend the hens. 3. Weaker roosters must be separated from aggressive roosters as they can be hurt or killed. 4. Roosters need hens, 5 or more should keep them happy. 5. Most important, they need food and water.
