Hi Dr Mike,I have a very itchy bird and I was wondering if it could be yeast-what are the symptoms?I have a vet appt tommorow but I was wondering what to test for?We have discussed Caspian before re Bachs Flower remedies.In the last 2 days he has started scrarching and plucking the feathers over his crop-he acts uncomfortable-always itching with his claws or obsessivly preening.He itches his head and chest-somewhat on his legs.Any hints.Thank you Marla
