They do not like them at first. They get used to them quickly though.Thanks Ron. This is cotton fabric and I just sewed on spot on each end of the fabric as I have to go get some more velcro maybe at the fabric store. I put the little collar on a year old rooster that does crow and he faught it so hard then laid down like he was going to die. It was not that tight I put my finger between the collar and his neck. But I loosened it up more and will tighten it some more tomorrow and see how he does. I really need some more velcro so I can make several and see which style might work better.
