I thought I would do an update in case anyone is still wondering about doing these collars. On return from my vacation-we tried to put the collar back on our boy. He did the usual backing up into things and not happy-but this time it was much more than 10 minutes. we sat out there for an hour and a half as I was afraid to walk away. He would not walk forward-only backwards - throwing himself about, sitting there looking depressed. it was not tight AT ALL-we were just trying to get him used to it. SO we removed it-and that little stinker jumped right up and was completely fine. Just a drama queen. So I let it go for a few days but he is loud and bottom line-it's not allowed where we live. Without my husband sitting there-I put it back on-drama lasted 10 minutes-and then he was fine. I think he was truly playing us. Little by little I've been tightening it-right now I'm at the point where I will not tighten it anymore. he is still crowing-my neighbor 3 doors down can hear him-but she said not loud -he sort of fades out at the end. This will probably be as good as it gets for us-we will take the chance and keep him, it did lower it as long as folks are ok that are closest to us-I think this will work. You just really have to take your time and monitor them. He is a beautiful rooster - and so far he is kind and loving. hoping he is here with us for years to come.
