I once had a very old bantam Cochin roo who's spurs had grown so long that they were actually curving back around, under and into the bottoms of his feet! Due to the fact that I don't snuggle my birds and because of all his feathers covering his feet, I didn't notice the lengths of his spurs until he was walking funny!
Anyways, I had heard once that all you have to do is twist the spur back and forth and the hard part should come off like an antelope's horn sheath. Well I tried this and of course it didn't work for me! I must not have been biting my tongue on the correct side of my mouth that day I guess. Seeings how the rooster was not digging it too much, I thought I would just trim them back with a pair of K9 nail trimmers instead and let him be on his way. I knew that I would have to be careful not to trim too far, but I had no idea how long their flesh nub went inside that spur sheath!!!
I started trimming a bit at a time because of how twisted the spur was and then I thought I could see the quick when I was attempting the final snip, but thats right, I was wrong! I sniped it just a bit too short. He wasn't bleeding bad at all. It was just starting to leak though very slowly. Nothing that a rub of the styptic pencil wouldn't fix!
I thought OK, now I know what I have to do for the second one. Wrong again!!! This flesh nub was even longer than the other side! And despite my efforts to leave more spur this time, it started to spew blood badly!!! I knew the pencil wasn't going to work for this one so I happened to have a little propane torch handy so I heated up a framing nail and cauterized it!
I know it sounds bad, but it stopped the bleeding and that little rooster was better than normal in a day or two!
