Hello everyone, I started with my budgies about 5 months ago and have learned a lot. Yet I am still very green on this subject. I have 6 budgies in a cage and 2 budgies in another since they old enough to breed. I misunderstood a comment I read for home treatment for beak mites and I began to mix olive oil with the bird's sees. I have noticed that a few of them have feathers missing on the sides of their beaks. Does anyone know if the feathers will regrow? Or has the oil burned the feathers for good?
