My first chickens were day-olds in May. I have 4 cockerels and 18 pullets. Can I have more than one rooster? When will I see how good a rooster they would be? Is that possible to predict? How do I know who would be a bad rooster? One is an EE. One is a Hampshire/Delaware cross. Two are Welsummers. The EE is 3 weeks older and crows on occasion. They are ALL in the coop together. So far so good.
