Hi, I was wondering if anyone would have any idea what this could be on my Aussie's neck? I just noticed these bald spots today. I have noticed for a few weeks that there are a few of those small feathers in the roost in the mornings when I go to clean it? I mean 2 to 4 little feathers maybe... nothing crazy or anything! I don't see any bugs on her or in the coop and roost. I am baffled and any thoughts or ideas on what could be causing this will be very much appreciated. Thank you most sincerely!
