Two months ago has bought young cockatiel. It under a cop had naked place. The seller has promised, that it will be over. But it has not taken place.
Really, nestlings cockatiel under a cop can not have plumage, but with mature a parrot this place grows. Not overgrown the naked site at an adult bird can specify that actively used her parents for reception of posterity. Such birds frequently have shortage of vitamins and mineral substances.
The site on all life remain naked, but it does not influence in any way health itself Cockatiel.
