Good. Thank you very much!It is shed intestinal lining. At that age it is quite common in my experience. As long as the bird isn't displaying any symptoms of ill health and it is a one off occurrence, then I would not be concerned. That said, I do have Amprolium in my animal first aid cupboard so that it is there if they start to look ill and I need to use it at short notice but I have had it 4 years and I'm yet to break the seal!
