Coccidiosis is a common and often fatal disease of finches, especially during the juvenile moult. Finches housed outdoors are most at risk and should receive coccidiosis prevention.
Coccidiosis should be assumed to be present when several juveniles of the same species are found fluffed up on the floor.
