I got some sexed hatchlings last February and I've finally come to terms with the fact that one of them must be a rooster (no crowing or spurs quite yet, but we haven't had any eggs yet and this bird is bigger and more adventurous than the others). I've read online that there is a certain ratio you need to keep if you keep your rooster, or else they will become overly aggressive towards your hens. Is this an "always" rule? Or can I just wait and see how our rooster does? He seems totally non-aggressive so far, so I really don't want to re-home him right now if I don't have to.
