I can see down feathers that are prominant.Where are you seeing bare patches?
He is 7 and I never noticed such bald patches. I have found feathers on the floor and they are intact.Ahh okay I do see that. It could potentially be plucking or barbering; how old is he?
If it it's indeed plucking, and especially if it's localized, I would be talking to my vet, as plucking can be a symptom of pain or illness. Best to rule it out at any rate!
I will monitor and make a vet visit.Any sudden changes warrants a vet visitif nothing is physically wrong, you still have that peace of mind, and have ruled out one possibility.
