You have to wonder if Nico's past diet damaged his organs or system in some sort of permanent way. I dont think anyone knows for sure what long term irreversible damage is done to these birds when on the incorrect diet for years. Like people can develop permanent diabetes due to years of poor diet (either by choice or no fault of their own). Nico is lucky to have you now and no matter his medical issues...im sure he's feeling better under your care. Im currently contemplating adopting a male ekkie at a local rescue...he is very very feather picked. I know that even with the correct diet now, there is a good likelihood that he will always be feather damaged/picked due to past incorrect diet/neglect, etc.
Sophie has a tendency to pick through her chop and only eat what she wants...so there is alot of waste unfortunately.
