Your roosters are your roosters do as with as you see fit.
Many if not most people on this forum keep roosters as a first (or maybe it's a final) line of defense for their hens. Whacking or burning off your roosters' spurs makes about as much sense in my book as an Old West cattle baron hiring a gun fighter to keep his cattle safe and then chopping his hired gun's trigger finger off. Oh Well!
Refer to my first sentence.
Some times these spurs do more damage to the hens than they are worth....
I had a gash three fingers across on one of my hens from a rooster mounting and slipping wrong...
Doesn't always happen, but I do think spurs should be at least filed back to a safe (for the hens) length.
Besides, a rooster doesn't stand a chance at most predators. Spurs or not. Their job (for me) is to warn and protect, but usually the roosters are doomed to get killed if they are the only line of defence.
