What do you feed roosters?
Our roosters eat the same feed as the hens. It is a basic ration for egg laying poultry purchased up at the tractor supply. They also get veggie and salad scraps from the kitchen. They don't mind getting into my garden and eating my greens and strawberries either.
Roosters go through a full molt about once per year, usually as the season changes and natural light levels are reduced. This is not cause for worry, Hens egg production will drop and the roosters can look a little disheveled. They put a lot of energy into replacing feathers lost during this time and a good nutritious feed is required.
