I'm looking at getting a Light Sussex cockerel to join my flock and have a couple of questions. 1. My pullets are currently around 24 weeks old, when you get a cockerel is it better if he is around the same age, older or younger? 2. I currently have 3 hens, would it be necessary to buy more if I was to get a cockerel? 3. Would you still eat the eggs even though there is a chance of them being fertile? The reason for getting a boy is I hope to raise chicks in the future.
