I have a 5 and half month old buff orp cockerel, and he hasn't grow any spurs or lil bumbs on his leg, i know hes a roo cause crows & has the rooster tail, I was told they get them at 6 months, but in 2 weeks he will be 6 months shouldn't he have bumbs or any sign of his spurs growing? Or is it possible hes not goin ti get them? Thanks
