I have had this bird a long while and just a couple of weeks ago I noticed his chest feathers gone. While my mom was helping me take pix she notcied he took one out. I have no clue what to do. I have another bird, and they are a mating pair. I took the mating box down and put dryer lint at the bottom of the cage. Then a week later I noticed it. My grammy came over and looked at it and said to take the lint out. He may be allergic.I did and it has been a week, I don't see any progress what can I do?
