Yellow crust on African Grey skin
Hi, I have a 5 year old african grey timneh. He is currently eating zupreme fruitblend pellets and taking additional clacium and vitamin supplements. He has previously received treatment for a respiratory tract infection about a year ago that I believe was a mixture or fungus and bacterial origin for this he was treated with enflucloxacillin and has no symptoms of any nasal infection.
A few days ago I noticed a malodourous smell coming from under his wing, upon inspection I realised he has some feathers missing and a crusty yellow film that appears to be encrusted to the skin, just above this he has a very small broken area which appears to be healing. There are no signs of infection around the area i.e no redness, swelling or changes in temperature of the skin. I was wondering if this could be a fungal infection? Thanks.
