Hello! I知 sorry if this is the wrong thread but I知 new here and needing some help. I致e owned many types of birds for many years but have recently encountered something I知 not super familiar with. My 3.5 year old goffin cockatoo has started what may be plucking? I have a pionus that plucks but under his wings, I see his bare skin and what looks almost like holes... some with black in them. (Not pin feathers coming through) Weird and difficult to describe. Trying to understand what I知 actually lookin at and if he is indeed plucking. (The rest of his body looks fine featherwise. Haven稚 seen much of a change in the condition of feathers under his wings in the past month. He has molted a bit but not much. Has a cage mate and a million toys.)
