Inspection done, and I think they're good. Lots of dander/shed feather sheaths, but I dont think there's any lice. However, I saw this poop when I opened them up this morning, and it caught my eye. I believe based on pictures I've seen that this is shed intestinal lining, but can anyone confirm? Finally, I believe when I was reading about mites I read that they leave black marks on the feathers. I have seen no evidence of mites, but there are black spots on the tail feathers of one of them. Only on the tail feathers, nowhere else. Normal? Thanks to everyone for the help!
