Not sure how to describe it. I have checked for lice/mites cant seem to find anything. Tails are looking straggly, on is missing feathers off her chest. Seem to have black spots on some of them, little tiny black dots. (cant find that this is lice/mites) the spots arent moving. They are 7 months old, a little young for a molt. I was thinking of dusting with sevins to rule anything out....not sure though.. Any thoughts?
