if you can insert a pencil then should be ok. Since my rooster adapted with velcro, I am thinking to go to Joan'n Fabric store and get a wide rubber band instead.
I have a silky rooster and love him dearly, therefore, no option to sale nor give him away. I bought 2" velro and wrap around his neck and it does reduce!! Also, I tap him each time he crows with "noodle" kid use for swimming. No he realize he will be tapped with a noodle, so much much much...
