I could never put a no-crow collar on a rooster, or a no-bark collar on a dog.
		
		
	 
No crow collar function is to reduce the volume of the sound, the rooster still crow and mine did crow his mighty crow.
We as a family did not want the no crow collar for our baby rooster when he started crowing, the option is to rehome him to a farm, or animals rescue people. The breeder happy to take him back and ...as you can imagine..food he will be.
We were facing with the decision of what to do with him, he was so cute and he followed me everywhere.....eventually we came to the decision that to live..he has to wear the collar, and so our lives and his changed since.
My old rooster had a life, it was with the collar but not all day wearing it.  IF he can talk what would he say? He stretched out his wings in the sun, did many mating dance, he was a good rooster and was loved.
If you have a rooster and not allow to keep it, you will be facing with what to do, how to find him a good home to go to.  If you can find him a good home then that is wonderful. A good home means he is loved, cared for and get to live out his rooster life.  I wonder what happened to those roosters that were rehome, will many find a good home?
I did rehome my 2nd rooster to an animals rescue farm that was so well liked by all, a month later we took him back and he was near death. If we did not take him back he would had suffer and died after a long suffering illness. No one cared for him. They told us he was beaten by other roosters so they locked him in a cage.
When we got him home, he was very sick, barely much energy to move and covered in lice/mites, sour crop, runny nose..etc, he looked and walked around the garden, he remembered his old home.
We all make decision that we can live with, each situation is its own.
