Crowing rooster

[chickenlady02]

Hey guys, I've been looking at a rooster collar. I've been seeing that they work by not allowing the rooster to get the amount of air needed to crow. I would like to know whether this effects the rooster in any way? And does it have any long term effects? I really would not like to give my rooster away so this is the last option
Thanks
