Hi everyone, good morning. I have a bit of a question in connection with Rockys feathers, particularly just above his Cere. I have noticed that they are turning brown which is concerning me. Apart from that he is eating normal and active, my first instinct is he needs more fresh foods in his diet and he is such a picky eater. Put anything new in his cage and he is extremely wary so unless itís Basil or Mange Tout he doesnít want to know. I am also worried that it could be the start of something more sinister so please could I have some advise. Please find attached photo.
