I have a flock of hens and 3 roosters. The roos are all around 18-20 weeks old now and one is already very aggressive. I am thinking of despurring him because the spurs are less than a quarter of an inch long, and I read this is the time to do it, if ever. My question is, HOW? Do I use a knife and just cut them off and put something on to stop the bleeding? What is the best way to catch my aggressive roo without getting hurt in the process? (at night when he's already roosting?) Any ideas would be most appreciated! Thanks!!
