Dead Head Syndrome
I deal with it fairly frequently. Can have multiple causes. Sometimes you have a wus. But just as likely your bird is stressed by a parasite load. I assume your knowledge of nutrition very good.
For wus. Isolate him in pen, no ladies, no dudes for a week or two. In addition to usual fare, feed him treats (insects or fruit) from hand to relax him. Then start handling him and giving him a workout like with a fly table. Working muscle groups can produce testosterone just like testes. When you want him to act like a breeder, introduce ladies to him but keep numbers low.
If he is possbly wormy, as some birds prone to become when confined to eat in same location where they defecate, then treat him for such. If wormy, improvement will be rapid.
