Spurs

Lots of hens have spurs and they are not usually a problem, it is just the breed or the way they are bred. If they become a problem it is very easy to remove them with a pair of pliers (have some purple spray handy when you do it)

I have two Buff Orpington Cockerels who are actually very tame (as this breed tends to be) but they are big birds and cause damage to the hens even without be aggressive. I have de spurred them twice each, they grow back but become 'stumpier' (if that is the right word) i.e. the point of the spur eventually becomes just a nub.

Emily one of my girls has big spurs, quite normal

You don't actually cut them off with the pliers. Hold the bird under one arm and, taking one leg firmly in your left hand (if you are right handed) you put the pliers around the spur and give it a firm twist, the spur will come off in one piece, it should look cone shaped and hollow. There should be very little bleeding but use purple spray to stop any and protect it from infection. I have only ever de spurred cockerels so, unless it is causing your hen a problem, I would leave her.
