Can any-one help I have a bird that has a strange patch above the bit above the beak,its like a brownish orange area,he is still eating and drinkinking but spends most of his time sleeping,with head tucked under wing and ruffled feathers,other strange thing is bird use to fly ever where but suddenly stoped flying,any help would be great

If no longer flying and behaving as normal A visit to an avian vet may be in order.
