Barred Rock (dual purpose) keeper here. Checking my breed selection and thinking of adding a second breed. Having some questions regarding Leghorns: 1) by how much can you save on feed by raising and keeping leghorns for eggs instead of Dual Purpose? 2) are they less hardy / more miserable in the winter being smaller/skinnier birds and with large combs? 3) at what age Leghorn cockerels can be sexed out? 4) would you raise excess Leghorn cockerels for meat and to what age and dressed size? 5) would you process old age hens for meat and how would it compare (taste and dressed size wise) with a DP chicken?
