Does caponizing alter the frequency of crowing? Would you reccomend the procedure for someone who would like to keep a favorite chick (who of course wound up to be a cockerel) in a no rooster neighborhood?
Caponizing will stop the desire to crow, mate and fight, as stated by QueenMisha. Capons will develop the same colors and feathers as a roo without the large red comb. It is a perfect option for pet cockerels in the city, but I must caution, it is VERY difficult to succeed with an older roo <16 weeks or so (I would suggest starting with 6 to 9 weeks). The testes get fragile and the stress is much greater on the bird.
