Hi, My Parrotlet has been poorly for a while. I was advised to try Guardian Angel which I then changed to Avipro Avian (which seemed to help a bit). However he doesn't appear to be progressing very well and is still not eating as normal (again, on advice, we cut back normal diet to normal seeds and millet to make it as easy as possible for him to feed). In addition, he appears to have what seems like dark scabs either side of the corner of his beak (which is clearly upsetting him as he wants us to scratch them off for him!) Can anyone help?
