I have a two chicken limit on Oahu residential zone, but I have 5 roosters and 17 hens. I gave one of my neighbor chicks and gave the other eggs and my neighbor in back raise chickens, so no one complained yet.Thank you I'll experiment with this a little more!
I make my 1 1/2 inch velcro collar as tight as need be to get the sound I want. I mark my black velcro collar with white out during the adjustment and I move it 1/8 inch at a time.
I notice that certain blood lines can't wear them like one of my Breese lines. The skin on its neck is too thick. I think Green Fire farms brought in two lines and I have both of them. One of their lines can wear rooster collars and one can not.
If your rooster is wearing them and is still alive it should be okay to make the adjustment to the sweet spot.
I can barely hear my one year old rooster...........
