Ok I am resigned to the fact that my cag is a plucker have tried everything under the sun and the avian vet says medically he is healthy. well he plucks till he bleads under his wing and then he picks at it. around and around we go vet gave me collar well I put it on him and when everything is healed it usually comes back off but right back he goes. My question does anyone else have this problem and if so do you ever take the collar off it just looks to cruel and he has a hard time with it.
