2nd visit to the vet Collar No 1

On the second visit to the vet we after we had tried everything we could think of we agreed that the vet would put a collar/cone on Spooky so he would stop plucking. It was the only thing left to try. The vet said to leave it on for 4-6 weeks. The photos shows how unhappy he was with his collar/cone on. After the collar was put on Spooky did not whistle or talk for 3 weeks and mainly just sat in his cage with his head hang down, we felt so sad for him and wondered if we had done the wrong thing we wanted our old Spooky back yes he was plucking feathers but at least he wasn't miserable. Also his neck looked really sore where the collar sat it seems to dig into him. There had to be a better option than this.
