Wow Mike, you have made good progress and I applaud you on that, truly. I can feel the exhaustion in your post, mostly because I have lived it for TWO long years
. From personal experience, don't touch the collars, great in theory but there is a down side. We finally resorted to collars, worst decision ever made, turned into a giant mess that resulted in a large wound
. What diet are you feeding? Perhaps he may have an allergy? My flock is now getting switched to a combination of Goldn'obles I and TOPS, if that doesn't work then we are cutting out anything with corn in it.
Are you using tap water to bathe him? I don't know what water system your using but over here in the fine city of Eustis they have changed it (not sure what they've done but I can taste a difference). We are using Harrison's rain water now for bathes. You may also want to try Harrison's soothing spray until he calms more then switch to the rain spray. Just a suggestion. I have tried everything with Rome (collars - hated, drugs - absolute worst thing ever did hands down, 24/7 supervision - exhausting but does work problem when you cant be around, aviary - beautiful but she cant get past her plucking to utilize it, Now I'm doing the diet change eliminating anything with artificial dyes and preservatives and feeding organic only and trying the rain spray-crossing my fingers and toes).
We have actually resorted to sending Rome to an actual birdie boot camp at MARS in Melbourne for a month. We had to remove her collar because of a wound (that occurred from her hitting it against something). All of her feathers had grown back in, within two days she plucked her chest bare and started creating a wound on her chest. After two years of exhaustion I had my breakdown. We get her back in a few weeks, I'm taking this time to regroup myself, breathe, and for plan - was going to say B but at this point I think were closer to T or Q. Good luck Mike, its not an easy road but your definitely not walking it alone.
