The shed, perches and nests should be sprayed thoroughly, making sure the spray gets into crevices. All birds need to be de-wormed regularly for roundworms which are the main problem, although tapeworms, hairworms and caecal worms can occasionally cause problems. If birds are sick A diagnosis from a qualified person should be obtained as soon as possible if the birds become sick. Many diseases cause similar symptoms and it can be difficult for the unskilled to make an accurate diagnosis. When the disease is identified, the right treatment can be given.
Management is as important as the use of drugs in controlling and treating disease.
