I'm having a hard time with finding the right placement/fit on our leghorn Roo. Its either too loose and does nothing or just tight enough that it throws his pitch so its actually louder! Ive moved it up and down on the neck no change. I can still place the tip of my finger underneath but I have tried varying degrees of thightness. Right now its at the base of his neck. Figertip tight. I know its possible, the very first time I applied it I woke up cheering because while I heard him it worked he was so much quieter (10-15%). But the hens managed to help him adjust right on out of it. And I've been struggling ever since. Help!
