I used the way described on youtube and I've put the link below
Removing Rooster Spurs
OMG really! I think this is a bit OTT it is the equivalent of ripping a finger/ toe nail clean off with pliers.
I'm sure clipping the spur back and filing as FF explains is much more appreciated by the cockerel.
I can understand the feeling that this seems possibly unpleasant, I too worried about this at first. However, my older cockerel had very badly damaged two of his girls and they all were developing lacerations on them. We increased the number of females available to him but it still happened. His spurs were very long and were split which I think was making them more damaging. I thought that this was an appropriate response and certainly with his shorter, smoother spurs he causes little or no damage to the females.
The spur itself is insensitive, it is the
quick in the middle which is sensitive to pain. As long as you do not bend or twist the quick while you are doing this the cockerel will not be distressed.
My worry about clipping or filing is that the quick extends up to 2/3rds of the spur. If you clipped into this (or filed it) it would be very painful and also would bleed profusely as it is quite well supplied with blood vessels.
I haven't tried using the hot potato method. I can see that this may make removal easier by softening and loosening the spur. However, I was concerned that the cockerel has to be restrained a bit longer and the restraint is probably the worst thing from the cockerel's viewpoint. I also wondered if they may bleed a little more after heating as it might cause some local hyperaemia. Although the heating is supported in the poultrypedia site (see below) so I'd be keen to hear what people have found in doing this.
