My town allows pullets and hens but not cockerels or roosters. The lady from the health department allowed me to give the no crow rooster collar a try but I just couldn’t bring myself to collar my boy, so I rehomed him. Since then I’ve had to rehome my first flock thanks to my neighbors being jerks. 
I’m getting a trio of silver sebrights and a trio of golden sebrights in March. The cockerels are going to be kept inside as house chickens so I can keep them. But I’d really rather if they could stay with the pullets because I love seeing them interact with the girls, and with an all pullet/hen flock you miss out on seeing these interactions. Now before anyone goes and says that it’s not right to keep them inside, the alternatives are being used for food or cock fighting. So my questions are for people who have used the No Crow Rooster Collar:
1. How long did it take for your cockerel or rooster to adjust to having the no crow collar on?
2. How much was the volume and frequency of crowing reduced with the no crow collar?
3. We’re you able to keep your cockerel and rooster after you collared him?
Anyone can respond with their 2 cents, but this post is really aimed at those that live in a town that allows pullets and hens but not cockerels or roosters, and somehow or another you ended up with a cockerel/rooster that you wanted to keep, and used the no crow rooster collar as a means to keep your beloved pet. I need honest answers from people that have used or are currently using the no crow rooster collar. I have read the online reviews and I know that you have to be meticulous in checking that the collar is not too tight or too loose on the cockerel or rooster. I plan to check their collars everyday. Thanks in advance for your answers.
