I have a bantam rooster (bantams are a lot smaller then regular hens) and we have crowing collars but he keeps taking it off. Also it is hard to get it to the bottom of his neck and when we do it has to be big to stay on and he loosens it and gets it over his head. Do you have any suggestions to help? We bought normal collars and make the length shorter but does the width need to be smaller too.
