Well, for one thing, it seems to me that their diet is way too high in protein. I don't know if you are aware of this but amazons only require 17% protein when they are breeding, the rest of the time, it should be much lower and, as our birds don't breed, it should be lower all the time although, if you keep them at a strict solar schedule, you can increase it a bit during breeding season so as to reinforce the circannual cycles. And the one-on-one at night is a no-no, they need to be on a solar light schedule so, once the sun begins to set, it's beddy-bye time for them. The thing is that keeping them at a human light schedule and feeding them too much protein makes them overly hormonal and that means a screwed up endocrine system (which governs everything in the body: molt, appetite, sleep, immune system, sexual hormone production, etc).
Just two more comments. I have found that feathers on the head take much longer to be replaced than anywhere else on the body. I have a male Senegal whose head got plucked by a now deceased mate and, although it has been years, he still has a bald spot that has not gotten 'filled up'.
Also, I don't know exactly what you mean by 'tried to get them to interact' but what I do is open the cages doors, walk away and, pretending that I am not paying attention, watch them carefully for any sign of aggression and, when it happens, scold the aggressor and move him away from the other one. Three strikes will get a 5 minute time-out in the cage. The other thing is timing because the best time to do this is at noon when they normally rest and are much calmer. It cannot be done during one-on-one time because they never want to share. And it never works if the birds are overly hormonal because there is no way you will convince them to accept an 'enemy' as a 'friend' if all they want is your exclusive attention.
Oh, and another thing, please do NOT use UV light! It's very dangerous to birds! What you need is a good quality full spectrum (CRI 94+ Ktemp closer to 5000 than 5500).
