My Americauna has some white/gray spots growing on her crown (noggin I like to call it). At first I thought it was frost bite or just dirt from her baths but now I see it slowing spreading. It hasn't infected the other birds but it looks like a fungus. A local store said to treat it with Blu-kote spray. I sprayed some on a q-tip and applied once. Is this enough? Should I re-apply and if so, how much how often? Otherwise she seems perfectly normal.
