My friend found a baby Delaware rooster on the street she brought him in and he does not have any disease. He's at least almost a year old and hasn't crowed once or attempted to mate. Yet we have some silkies way younger and they crow and mate already. Poor Delaware rooster is petrified of everything that moves. He shoves himself in a corner in the coop under a ramp and. He breaths so heavily when he's scared. WHATS GOING ON???
